1 Fabrication And Testing Of Sugarcane Baggase Ash Partially Replacement As A Cement Madireddi Sai Madhav 1*,P.Meher Lavanya 2 M.Tech Student 1, Assistant Professor 2 Dept.Of Civil Engineering Kakinada Institute Of Engineering & Technology-II, Korangi Abstract: Concrete is the most widely used construction material. It is produced by mixing cement, fine aggregate, coarse aggregate and potable water. Increase in demand and rapid growth of construction industry results in the need to identify alternative materials for coarse aggregate and cement. According to increasing demand and consumption of cement the industry need to develop alternate binder that are environment friendly and contribute towards sustainable management. Sugar Cane Baggase (SCB) which is a voluminous by-product in the sugar mills when juice is extracted from the cane sugarcane production in India is over 300 million tons/year that cause about 10 million tons of SCBA as unutilized and waste material. SCBA has been used in this study to replace the cement by weight using different percentages (0%, 5%, 10%, 15% & 20%). In the first part of this thesis, the background of the study and the extent of the problem were discussed. I. INTRODUCTION Generally (SCB) is used as a fuel to fire furnace in the same sugar mill that yields about 8-10% ashes containing high amount of un-burnt matter, silicon, aluminium, iron and calcium oxides. But the ashes obtaining directly from the mill are not reactive because of these are burnt under uncontrolled conditions and poses disposal problems. SCBA used in this study was obtained from industry in W.G.Dist, A.P. An attempt made in this experiment is partial replacement of cement with different weight percentages of sugarcane baggase ash concrete subjected to different curing environment. The properties of concrete investigated include compressive strength splitting tensile strength. Concrete is the most widely used building material. It is versatile, has desirable engineering properties, can be moulded into any shape and more importantly, it is produced with cost-effective materials. Although recent development in plastics and other lighter materials have resulted in the replacement of concrete in some application, the use of concrete worldwide has increased phenomenally and improved the performance and use of concrete in structures. II. MATERIALS & METHODS A. Materials Cement: Ordinary port land cement of 53 grade from a single batch was used for the entire work and care has been taken it has to been stored in airtight containers to prevent it from being affected by the atmospheric and monsoon moisture and humidity. The cement produced was tested for physical requirements in accordance with IS: Sugarcane Baggase Ash: Sugarcane baggase consists of approximately 50% of cellulose, 25% of hemi cellulose of ligin. Each ton of sugarcane generates approximately 26%of baggase (at a moisture content of 50%) and 0.62%of residual ash. the residue after combustion presents a chemical composition dominates and that presents few nutrients,the ash is used on the farms as a fertilizers in the sugarcane harvest. In this project sugarcane baggase ash was collected from jaipur sugars limited, chagallu, W.G.Dist.

Fine Aggregate: The river sand, passing through 4.75mm sieve and retained on 600mm sieve, conforming to zone 2 as per IS was used as fine aggregate in the present study. The sand is free from clay, silt and organic impurities. The aggregate was tested for its physical requirements such as gradation, fineness modulus, and specific gravity and bulk modulus in accordance with IS: The materials are mixed for M 20 grade of concrete as 1:1.5:3 of cement: fine aggregate: coarse aggregate and taken the water cement ratio 0.48 for this mix condition the materials are weighted accurately. C. Mould Preparation A mould with dimensions of 150x150x150 mm is used during the process to prepare the required composite. A grease is applied to the inner surface of the mould for reduce the sticking of composite. Fig 2: SCBA Fig 5: Composite Mix 3: Coarse Aggregate Fig Fig 4: Fine Aggregate B.

Fabrication of Composite In this project total 21specimens are prepared in a mould 150 x 150 x 150mm for compression test and 300 x 150mm diameter mould for tensile test & 150 x 150 x 700mm for flexural tests. The specimens are filled by concrete by 3 layers of moulds each layer tamped by 25 strokes using damping rod. After the specimens are stored in a room temperature for 24 hours. After completion of 1day the specimens are taken out from moulds and placed in a curing tub for 3, 7 & * corresponding author Page 21

However, tensile failure the specimens are casted for different weight percentages of sugarcane baggase ash concrete were tested with the cylinder axis horizontal and applied diametrical compression as per IS: 516 for determining splitting tensile strength. The split tensile strength for the cylinder specimens are calculated as Split tensile strength = 2P*π LD Fig 7: Manual Compacting Fig 8: Compression Test Machine Fig 8: Fabrication of Composite III. Testing of Composites A. Compression Test The compression testing machine used for testing the cube specimens is of standards make. The capacity of the testing machines is 2000 KN. The machine has a facility to control valve. The machine has a facility to control valve. The plates are cleaned and oil level is checked, and kept ready in all respects for testing. After the required period of curing the cube specimens are removed from the curing tubs and cleaned to wipe off the surface water. It is placed on the machines such that the load is applied centrally. The smooth surfaces of the specimens are placed on the bearing plate. The top plate is brought to contact with the specimens by rotating the handle. The oil pressure valued is closed and the machine is switched on. A uniform rate of load 140kg/sq.cm/min is required or maintained. B. Tensile Test Concrete is not usually expected to resist direct tensile forces because of low tensile strength and Fig 9: Split Tensile Test IV. Results & Discussion 1.

Conclusion 1. The compressive strength of concrete (with 0%, 5%, 10%, 15%, and 20%, weight replacement of cement with SCBA) cured in water for 3, 7, & 28 indicates that the compressive strength decreases from the replacement percentage 15% & 20% compare with normal concrete. 2. The split tensile strength of concrete with 5%, 10%, 15% and 20% weight replacement of cement with SCBA have decreased with normal concrete but the C-5 value is low when compared to C- 10.The value of C-15 replacement gets the more value when compared with C The flexural strength of concrete with 5%, 10%, 15% and 20% weight replacement of cement with normal concrete. The value of C-10 is greater than the remaining mix proportions. VI.
