The type and dosage of Super-plasticiser to be used shall be subject to the approval of the Engineer-in-charge. The dosage shall be arrived at through lab. tests / mix design tests as approved by the Engineer-in-charge Types of concrete, strengths etc. : The Bill of quantities specifies various types of concrete. The strengths corresponding to these types is as per table below : i. Types of Concrete Sl. No. Type of Concrete 28 day Characteristic Design strength N/mm2 28 day Target Design Strength N/mm2. 1 M X 3.5 = M X 4.0 = M X 5.0 = 38.2 Note : The established values of standard Deviations shall be used. When adequate test results (30 or more) are available and the target strengths revised thereafter. Efforts shall be made to bring the standard Deviations up to date, preferably once a month. Even though the Bill of quantities specifies various types of concrete, it is possible that the type may be altered to suit the site conditions. The compressive strength indicated above pertains to compressive strength tests on work test cubes 15 x 15 x 15 cm, after normal curing for 28 days. The strength of preliminary test cubes shall be as per IS : 456. The type of concrete for any particular situation of work shall be as per drawings. Any construction in the coastal areas may be considered as exposed to severe environmental condition. In assessing the level of severity, it shall be prudent to adopt a realistic attitude and be even some what conservative in respect of the extent of coastal zone for the ultimate durability of the structures. Thus, besides using. Portland Slag Cement, the specific requirement on durability aspects, as per Indian Standard IS 456, in respect of the following parameters, must be met :- 75

76 Minimum Cement Content Maximum Water / Cement ratio Cover to Steel Reinforcement. All these requirements are related to the various environmental exposure conditions. The standard IS 456 classifies the environment into 5 levels of severity, that is mild, moderate, severe, very severe, and extreme. The parameters relating to minimum cement content and maximum water / cement ratio, as per IS 456, are summarized below along with the minimum grade of concrete :- Exposure Environment Coastal concrete sheltered from saturated salt air. Concrete exposed to coastal environment Concrete exposed to sea water spray / or in contact with aggressive soils / ground water Exposure Classification Plain Concrete Min.

Grade of concrete Arrangement for slump cone test shall be kept at site to arrive at workability whenever theengineer-in-charge wants to check at site. Arrangement for compacting factor test shall also be made to Tests for determination of strength of concrete. ii. Strength of Concrete As will be apparent from the Bill of quantities, the strength of concrete specified is the criteria and the contractor shall make every effort to obtain the strength by good quality. Control. In case of concrete, which does not obtain the specified strength at 28 days, such work shall be demolished and reconstructed to obtain the requisite strengths, as directed by the Engineer-in-charge. It has also to be ensured that the concrete conforms to the durability requirements viz. all requisite parameters concerning minimum cement content, maximum free water cement ratio and the specified cover to steel as well as good workmanship to obtain full compaction of concrete with non honey-combing in the finished concrete etc. have to be meticulously implemented on the job including fully efficient curing of concrete surfaces. To determine whether concrete in any particular part of the work is of the requisite strength or not, test cubes (works test cubes) shall be made from samples collected from the concrete being poured for the particular part and determined as per acceptance criteria detailed hereinafter. The salient features for the collection of samples is as indicated below. Testing of Concrete Cubes for determining Compression strength: 1. Quality 76

77 As specified 2. Compression strength Shall be as specified for the particular type of concrete. 3. Criteria for acceptance of work Part or element pf concrete work shall be deemed to be acceptable, provided the three cubes tested for 28 days strength conform to the following as per IS 456. iii. Acceptance criteria of concrete cubes. (As per IS 456) The Concrete shall be deemed to comply with the strength requirements when both the following conditions are met. (a) The mean strength determined from any group of 4 non-over lapping consecutive test: (b) Any individual test result complies with the appropriate limits in column 3 of the following Table-A Table A. Characteristic Compressive Strength Compliance Requirement Specified Mean of the Group of Individual Test Grade 4 Non-Over lapping Results in N/mm 2 Consecutive Test Results In N /mm M15 f ck X established Standard deviation (rounded Off to nearest 0.5 N / mm 2 ) f ck 3 N /mm 2 OR f ck + 3 N /mm 2 which ever is greater M 20 f ck X established standard deviation (rounded off to nearest 0.5 N /mm 2 f ck 4 N / mm 2 OR f ck + 4 N / mm 2 Whichever is greater f ck = 28 days characteristic compressive strength In the absence of established value of standard deviation, the following values of standard deviation shall be assumed, and attempt should be made to obtain results of 30 samples as early as possible to establish the value of standards deviation of the specified grade of concrete. Assumed Standard Deviation Grade of Concrete Deviation (N /mm 2 ) Assumed Standard M10 & M M20 & M M30, M35 & Above 5.0 The above values correspond to the site control having proper storage of cement weigh batching of all materials; controlled addition of water regular checking of all materials aggregate grading and moisture content; and periodical checking of workability and strength. Where there is deviation from the table, the values give above shall be increased by 1 N /mm 2. 77

78 Concrete shall be liable to be rejected if it is porous of honey combed, its placement has been interrupted without providing a proper construction joint, the reinforcement has been displaced beyond the tolerance specified or the construction tolerances have not been met. The concrete shall be accepted only after the contractor carries out suitable remedial measures to the full satisfaction of the Engineer-in-charge. In case of doubt regarding the grade of concrete used, either due to poor workmanship or based on results of cube strength tests, core tests shall be carried out. The points from which cores are to be taken and the number of cores required shall be at the discretion of the Engineer-in-charge and shall be representative of the whole of concrete concerned. In no case, however, shall fewer than three cores be tested in accordance with IS 516. Concrete in the member represented by a core test shall be considered acceptable if the average equivalent cube strength of the core is equal to at least 85% of the cube strength of the grade of concrete specified for the corresponding age and no individual core has a strength less than 75% Quantum of Cubes and testing as per IS 456. The minimum frequency of sampling of concrete of each grade shall be in accordance with the following. Quantity of Concrete No. of samples In the work (m 3 ) and above 4 + one additional sample for each additional 50 m 3 or part there of. NOTE: At least one sample shall be taken from each shift. 3 test specimens shall be made from each sample for testing at 28 days. Additional 3 specimen cubes be cast to determine the strength of concrete at 7 days. The direction of the Engineer-in-charge in this regard shall be final and binding. Batching and making of concrete: All batching of aggregates and cement shall be by weight. All the necessary equipment such as weighing equipment, devices for determination of moisture and bulk in sand, slump cone etc. shall be provided by the contractor. Concrete shall be machine mixed in appropriate mechanical concrete mixtures until there is a uniform distribution of materials and uniform colour and consistence is achieved and under no circumstances for less than two and half minutes. 78

79 A wooden board approximately 30 cms. X 40 cms. Shall be put up at the concrete mixture on which shall have been legibly written in English and the local language, the quality of concrete that is being mixed, the proportions and other relevant data Cubes: The size of cubes to be prepared and tested shall be 15 X 15 X 15 cm (6 x 6 x 6 ) Cubes each are intended for testing at 7 and 28 days respectively and determining the strength. Cubes tested at 7 days should give a strength of not less than 70% of the corresponding strength of structural members and also for works at various levels. It shall also be collected whenever the usual quality for a particular strength is suspect. The acceptance criteria of concrete cubes as given above and in IS: 456 is to be followed. The test results of the sample shall be the average of the strength of 3 specimens. The individual variation shall not be more than ± 15% of the average. If more, the test results of the sample are invalid Preparation and Testing of Cubes: Casting of cubes, preparation of moulds for the same, processing and curing the cubes and testing the same shall be as per detailed instruction laid down in the relevant Indian Standard as amended up to date Equipment modules testing etc. It is entire responsibility of the contractor to prepare and get the cubes tested and provide for all materials, labour, modules, equipment, faculty and charges for testing etc. The contractor s rate for concrete work shall be deemed to include for these and no extra payment whatsoever is admissible on this account Slump: The slump cone tests shall be required to be performed to establish workability and the same shall be carried out free of cost. Suitable Plasticiser / Superplasticiser may need to be used, as directed by the Engineer-in-charge, in M-20 M-30 & grade RCC to obtain therequisite workability of concrete at the specified water cement ratio Form Work: Form work shall be properly designed and constructed such that it is rigid enough to remain free from bulging, sagging or replacement during placing of concrete. It should also be so constructed as to facilitate removal of the same without damage to concrete. The formwork shall be adequately watertight to prevent any loss of liquid and grout. All formwork shall be accurately erected in regard to size, levels etc. In case of timber form work, the surface of forms in contact with concrete surface shall be wrought. The joints between boards shall be close fitting and very thin for the concrete surfaces designed to have exposed finish and not intended to be plastered. Surface of forms coming in contact with concrete shall be treated with approved emulsions or mineral oil. It shall be ensured that these emulsions do not stain or discolour the natural colour of concrete. All form work shall be removed as per latest IS 456. Form work shall be removed without shock or vibration. Edges of beams and columns if required to have chamfers shall be obtained by suitably 79

80 fixing triangular edge beads 20mm x 20mm to the forms. (No extra is admissible to the contractor on account of these incidental and minor works for sizes up to and including 20mm x 20mm). Likewise where drip notches are necessary they should be formed by suitably shaped fillets nailed in forms. Form work for all beams and other horizontal construction members shall be built to an upward camber of 1/300 of the span (in the center) to nullify the effects of optical illusion. The camber shall be in addition to such camber as may be required and shown in the Static Calculations. The tolerance on the shapes, lines and dimensions shown in the drawings shall be within the limits given below: (i) Deviation from specified dimensions of cross-section of columns and beams..+ 12mm - 6 (ii) Deviation from dimensions of footings 1. Dimensions in plan + 50mm Eccentricity.0.02 times the width of the Of deviation but not more than 50mm. 3. Thickness...± 0.05 times the specified Thickness. (iii) Plumb, specified Batter, the lines & surface of Columns walls etc.± 12 mm (in 3m of height) ± 18 mm (in 6m of height) & ± 30 mm (in 12m of height) After the forms have been erected to line and grade, the same shall be meticulously inspected as to their adequacy. If the forms are not tight, there will be loss of mortar, which shall result in honey-combing of concrete or a loss of water which shall cause sand streaking. If the inspection reveals that the forms are not braced sufficiently to stay in alignment during concrete placement, concreting operation shall not be commenced till the Contractor sets right the deficiencies and the forms re-inspected and found O.K. it shall also be checked during inspection that the formwork as erected conforms to the specified line, grade, alignment to the specified tolerance limits. Fully adequate rigidity of forms is of paramount importance since the tolerance limits specified are for the finished concrete and not for the forms. Consolidation of concrete by the vibrator requires that the forms be tight and strong. Stability is a very important consideration in the form work and the Contractor shall be made to understand that the common deficiencies resulting in failure of formwork. (i) Inadequate cross bracing: (ii) Inadequate horizontal bracing: (iii) failure to regulate the rate of placement of concrete in the forms and (iv) abnormal form displacements during & after concrete placement due to inadequate provision for lateral pressures. The contractor should ensure that ready access is provided for proper placement of concrete, vibration of concrete, and for inspection of these operations Horizontal Construction Joints : 80

81 A very common blemish on formed concrete surfaces in the off set often found at horizontal construction joints where forms have given way (viz yielded) a fraction of couple of centimeters at the bottom of the new lift. These off sets should be prevented by so setting the forms as to fit snugly & tight against the top of concrete in the previous lift and then securing the forms so as to remain in tight contact during the concrete placement operation. The anchoring shall be done by using an ample number of ties and bolts above and within a few centimeters of the construction joint. The ties in the top of previous lift cannot be relied on to prevent a slight spreading of the forms at the joint. Forms shall overlap the hardened concrete in the lift previously placed by not more than about 50 mm, though 25 mm lap is considered satisfactory. The Contractor should take utmost care to ensure that the construction joints are smooth, free from sharp deviations, projections or edges Spalling from the face of concrete : Occasionally, spalling may occur from the face of concrete when forms are removed. This is often caused by rough spots on the forms where mortar adheres strongly enough to overcome the tensile strength of green concrete. Such areas on the forms must be cleaned, polished and the covered with form oil by the contractor. Wire brushing of timber forms shall be done very carefully to remove the set-mortar Filling of Bolt Holes (she Bolts ) or Holes of ties / Rods. The holes left in the concrete surfaces by the She bolts or rods etc. shall be duly reamed, cleared, cleaned and filled with dry pack mortar by the Contractor within a reasonable period of the removal of formwork. Such filling shall be made flush with the concrete surface. No holes shall be left without the dry-pack mortar filling Inspection of Forms : The Contractor shall inform the Engineer-in-charge well in time (well before commencement of placement of concrete in the forms) to enable him or his representative to inspect the formwork as to its adequacy, suitability, alignment, strength and overall fitness. However, such inspection shall not relieve/ absolve the Contractor of his SOLE RESPONSIBILITY for the proper formwork, and safety of men, materials, equipment and the consequent results / consequences Transporting and Pouring of Concrete : No mixing of concrete shall be started unless the situation where they are to be poured are prepared and kept ready. Concrete shall be poured immediately on preparation. Transporting of concrete shall be done as speedily as possible and also in a manner to prevent segregation of aggregates. No re-tempered concrete shall be allowed to be used on the works. No concrete shall be allowed to fall from a height more than 1.2o Mt. Where the concrete is to be placed at more depth it should be done through chute as directed by Engineer-in-charge. Lift of concreting shall normally be not greater than 2.00 m in height. Before fresh concrete is placed against an already cast and hardened section, such surfaces shall be roughened, swept clean, moistened with water and treated with cement slurry. Fresh concrete shall then be poured as required. Under no circumstances, concrete mixed for more 81

82 than 20 minutes shall be used where initial setting has commenced. Dewatering of excavations for concreting where necessary shall be carried out by the contractor as directed and the rates quoted by the contractor are deemed to be inclusive of such dewatering. No concreting shall be done in adverse weather condition without proper precautions or approval from Engineer-incharge. No hand-mixing of concrete shall be allowed. In an exceptional / unavoidable circumstance, it shall be allowed under the specific approval of Engineer-in-charge and that too for a small or restricted quantity only, and in such a situation, 10% more cement shall be used than that used when concrete ingredients are machine mixed Consolidation and processing of Concrete : Concrete for all works shall be compacted by means of suitable vibrating equipment. Spare vibrators needles which are in complete working condition shall always be kept ready at sites to be put into commission incase of failure of the vibrators or needles under use. The vibrators shall be operated by skilled personnel, thoroughly instructed as regards the mode, frequency, duration etc. regarding vibration Finish to concrete surfaces : Finish to concrete surfaces at various situations shall be as per directions of engineer-in-charge. Where, form finish is specified, the final surface shall be smooth and even and no-undulations, ridges, spots etc. shall be permitted. They shall be laid to pattern as directed. In case surfaces intended and directed for form finish, exhibit any of the defects above mentioned, the surfaces shall be rubbed with carborundum and finished as directed at the risk and cost of the contractor. The decision as to the acceptability or otherwise of a surface will be notified by engineer-incharge and the contractor will implement the instructions accordingly. The honey-combed concrete shall be meticulously rectified to the full satisfaction of the engineer-in-charge Concrete Cover for Reinforcement : Where not specifically indicated in the drawings, concrete cover for reinforcement shall be as per the latest Indian Standards and as per directions at site from time to time. Proper concrete cover blocks to suite various covers as required shall be provided in adequate numbers sufficiently ahead of the work. In respect of the nominal cover to all steel reinforcements including links., it should not be less than the following to meet the durability requirement ( as per IS 456:2000) :- Exposure Environment Exposure classification Nominal concrete cover in mm not less than Concrete surfaces sheltered from saturated air in coastal areas Concrete exposed to coastal environment Concrete exposed to sea water spray / or in contact with Moderate 30 Severe 45 Very Severe 50 82

83 aggressive soils / water. The actual cover should not deviate from the required nominal cover by +10mm and - 0mm Construction Joints : Construction joints in concrete work shall be provided as far as possible only at predetermined places in consultation with Engineer- in-charge. Joints shall be provided as specified in latest Indian standards or as directed by Engineer-in-charge Curing : It is very important that all cement concrete work shall be cured properly. All concrete work shall be kept continuously in a damp or wet condition by pouring or by covering with a layer of moist sack, canvas, hession or similar material for a minimum period of 14 days from the date of concreting as per IS 456, prolonged curing beyond even 14 days shall be desirable (viz keeping the concrete continuously wet). Since the Water cement ratio of concrete shall be low (0.45 for RCC M30 grade concrete & 0.5 for M20 grade concrete as per IS 456:2000 Table 5), it is all the more important to ensure prevent of moisture loss from the concrete through fool-proof and prolonged curing. Water used for curing shall also be free from any deleterious substances and shall generally be fit for drinking. The work shall be adequately protected from drying, winds and direct sun rays. The contractor should arrange at his own cost a temporary water supply line with provision of suitable lines, pump etc. for curing and constructional purpose to reach all heights. The contractor shall not be allowed to commence the work of concrete placement until he makes all the curing arrangements to the full satisfaction of the engineer-in-charge (viz. water tanks, pumps, delivery lines, spray nozzles etc. as well as the requisite crew earmarked specifically for undertaking curing). Payment for the concrete placed shall be made only after its specified curing has been done to the full satisfaction of the engineer-in-charge Membrane Curing : Curring constitutes one of the most vital requirement for the strength & durability of concrete. Any slackness in curing or doing inadequate curring will adversely affect the durability of concrete. Fool-proof curring by the contractor is, therefore, a must. In case the Engineer-incharse finds that the moist curring(viz water curring) by the contractor is not being efficiently done (particularly on the under sides of slabs & beams etc.), he shall direct him to resort to the curring by membrane forming curring compound. The curing compound should be white pigmented of approved quality conforming to ASTM-C Type-2. This should meet the requirement of water retention test as per ASTM designation C Loss of water in this test for acceptable curing compound should not be more than 0.55kg/m 2 of exposed surface in 72 hours. The curing compound should also meet the day light reflectance test. Curing compound is to be sprayed with a nozzle. It should be applied as soon as the bleeding water disappears,leaving a dull appearance. This is when there is no free moisture on the surface. If applied too early, the free moisture will prevent the compound from forming a moisture-proof film. If applied too late, some of the moisture will have already been lost that should have been retained for the hydration process. Proper time range will vary from about 30minutes to 2 hours after placement 83

84 of concrete depending upon humidity and temperature.uniform coverage of curing compound on the concrete surface is very important and, accordingly, it should be mechanically sprayed with a nozzle. The dosage of curing compound sprayed on the concrete surface should normally be not more than 1litre for about 3.75m 2 (sq m) concrete surface area. The contractor shall be allowed to use the curing compound only upon his furnishing its test reports in respect of the water retention tests & day light reflectance test. The Engineer may also get the curing compound tested in a reputed laboratory for its suitability. Payment for the concrete placed shall be made only after the completion of proper application of membrane-forming curing compound Opening and inserts : All opening and inserts which are designated in due time or as required for services, will be exactly provided by the contractor including supply of materials. The contractor should also fix the anchors or such items which maybe supplied by the proprietor in exact position and in perfect lines and levels, inserts apply to such items as timber, dowels, bolts, loop, brackets, suspension, irons, hooks, screws, plates, pipe, pipe of various types and diameter etc. Openings in concrete or masonry must be provided in exact location, to correct shape, size and depth or slightly bigger, as shown in drawings or as instructed. It must be clearly understood that provisions of inserts and openings as contemplated in this contract are to be carried out with utmost precision and any deviation of the same from that as shown in drawing or instructed have to be rectified by the contractor at his own cost and responsibility. The contractor should make provision of openings to deep beams and their members at bottom or at lower level as necessary for cleaning purpose prior to concreting Steel reinforcement: All reinforcement for concrete work shall be corrosion resistance steel (CRS 42) and conforming strictly to the latest Indian Standards. They shall be of tested quality. Reinforcement shall be fabricated to shapes and dimensions shown on the drawing and shall be placed where indicated on the drawings or required to carry out the intent of drawing and specifications or as directed by Engineer in charge. Before placing, reinforcement shall be thoroughly cleaned of loose rust, coating etc. which would result in reducing or destroying the bond. Oiling the bars to clean them is strictly prohibited. Bending, straightening, cutting etc. operations shall be carried out in a manner not injurious to the material. Assembly of reinforcement, placing of reinforcement, Tolerance for Cover, welding of joints etc. shall generally conform to the Indian Standard specifications. IS Placing of Reinforcement. Before the reinforcement is placed, the surfaces of bars and the surfaces of any metal bar supports shall be cleaned of all rust, loose mill scale, dirt grease and any other objectionable matter. (ii) All reinforcement bars shall be accurately placed in exact position shown in drawings and shall be securely held in position during placement of concrete by annealed binding wire, and by using stays, blocks, metal chairs, spacers or other approved devices at sufficiently close intervals (less than 1 m interval) so that the bars do not sag. 84

85 (iii) (iv) (v) (vi) Wire for binding reinforcement shall be soft and of annealed mild steel of 16 SWG and shall conform to IS 280 The bars shall not be allowed to sag between the supports and also not allowed to be displaced during concrete placement. Also, the contractor has to ensure that no disturbance is caused to the reinforcement bars already placed in concrete. All devices used for positioning of bars shall be of non-corrodible material. Metal supports shall not extend to the surface of concrete except where shown in the drawings. Pieces of broken stone or brick or wooden block shall not be used. The contractor must ensure that the CONCRETE COVER AS SPECIFIED IS METICULOUSLY PROVIDED. All bars protruding from concrete and to which other bars are to be spliced, and which are likely to be exposed for a long period. SHALL BE PROTECTED BYA THICK COAT OF NEAT CEMENT GROUT. (vii) (viii) (ix) Reinforcing bars of 25 mm in diameter and less may be either lapped or but welded whichever is considered more practical by the Engineer. Reinforcing bars of 28 mm in diameter and larger may be connected by butt welding provided that the lapped devices will be permitted if found to be more practical than butt welding and furthermore that the lapping does not encroach on cover limitation or hinder concrete or reinforcement placement. Electric are welding shall, preferably, be used. Tolerance for Cover. Unless specified otherwise, actual concrete cover should not deviate from the required /specified nominal cover by + 10 mm Measurements: All reinforcement shall be bent cold. Unless otherwise directed, reinforcement shall not be spliced at points of maximum stresses. Engineer in charge shall be informed of the same before such splicing is taken up. Laps and splicing shall conform to the latest Indian Standards. Reinforcement shall be accurately tied at all intersections and laps with 16 SWG soft drawn binding wire, such that the reinforcement will give a rigid structure. Binding wire will not be measured or accounted for separately. The contractor s rate for reinforcement will be measured and paid for according to bending lists without allowances for cutting, wastage, binding wire etc. authorised laps, hooks, chairs, spacers etc. shall however be accounted for in case, the contractor or engineer desires to resort to welding or swivel nuts, there shall however be made as if the laps have been provided and no extra claim whatsoever shall be admissible on this account Reinforcement shall be assembled in place with proper concrete cover blocks to suite various covers as required. 85

86 All measurements shall be as given below or where not given as per latest IS : Concrete will be compensated for according to its actual volume. The computation will be based upon the construction plans only and no site measurements shall be taken for this purpose. All incidental work stated in the Technical specifications and also dewatering at the time of concreting are deemed to have been included for in the unit prices quoted by the contractor. Opening with an area larger than 0.1sqm shall be deducted from concrete quantity and where openings are smaller, these shall not be deducted. Form work will be measured and paid for according to their contact area. The unit prices of the forms incorporates all scaffolds, nails, clamps, and all incidental work. Openings with an area larger than 2m 2 shall be deducted from work quantities and the form work required for sides of such openings shall be paid for. Openings of less than 1 m 2 area shall not be deducted from work quantities and no allowance for from work for sides of such openings shall be made. Reinforcement steel will be compensated for according to the approved bending lists without allowances for cutting, rolling margin and waste.
