4 RAPIDOBAT Concrete technology Introduction The literature gives a wide range of instructions for the production and assessment of concrete surfaces, where specific demands on the surface appearance are made, on what are generally known as exposed concrete surfaces. A truly objective assessment of the completed structure is generally a difficult undertaking. Practice shows that the assessment can often be completely different in the respective views of clients and contractors. Even when the greatest care is taken, the final result can be one that does not do justice to the expectations arising from the construction contract. In particular, anomalies can occur during construction using in-situ concrete and smooth, non-absorbent formwork. In addition, irregularities in the exposed surfaces cannot be completely ruled out, even where additional effort is made. 1) The concrete surface The exposed concrete fact sheet recommends the use of one or a number of test surfaces for exposed concrete class SB2 and higher. These tests allow: the quality achievable under true on-site conditions to be determined; technical procedures to be developed or verified; the necessary effort to be specified and optimised; personnel to be instructed. If the properties of a test surface are agreed upon as a binding standard for acceptance, the surface is referred to as the reference surface. Factors such as uniform colouring, pore formation and flatness in the formwork skin butting zones (burrs, offsets) are assessed. The subsequent observation distance is, of course, taken into consideration in the assessment, as well as the knowledge that minor irregularities in the texture and colour are characteristic of concrete and specimens therefore cannot be reproduced without some deviation. 2) Exposed concrete classes Exposed concrete with Exposed concrete class Example Test surface limited demands SB1 Concrete surfaces with limited design demands; e.g.: basement walls or areas of predominantly commercial use Optional normal demands SB2 Concrete surfaces with normal design demands; e.g.: stairwells, retaining walls Recommended special demands SB3 SB4 Concrete surfaces with stringent design demands; e.g.: Structural engineering facades Concrete surfaces with especially high design relevance, representative structural engineering elements Strongly recommended Required Table: abstract from the DBV Exposed concrete fact sheet Example: exposed concrete class SB2 Example: exposed concrete class SB4 4

5 RAPIDOBAT Concrete technology for better solutions Concrete The production of simultaneously pourable and highstrength concrete requires the use of plasticisers. In order to prevent poor reactions, such as rapid loss of consistency, segregation or excessive delay in strength development, more detailed understanding of the interactions between plasticiser and cement or concrete is required. 3) 1. Placing and compacting the concrete Only after compacting and finishing the concrete acquires its final surface. The concrete should be placed and compacted in layers not more than a maximum of 50 cm thick in order to ensure that any trapped air bubbles can escape. The necessary compaction duration depends on the concrete consistency. If compaction is too short, the concrete grout cannot penetrate into voids and the result is gravel pockets or large cavities. If compaction is too long, the concrete settles and the danger of bleeding increases. The concrete surface displays considerable differences in colour and cloudiness. Additional compaction in the upper column region is recommended. 2. Concrete finishing The value of good finishing should not be underestimated. It clearly contributes to an improvement in the quality of the concrete surface. It enhances the impermeability and the compressive strength of the concrete surface region. The shuttering tube, once removed, can be replaced around the column to protect the reinforced concrete columns from mechanical damage. Rapid, differential concrete cooling can also lead to permanent differences in colouring. 1) Source: DBV Fact Sheet 2) Source: BetonMarketing 3) Source: vdz Recommendations Recommendations Thanks to constant quality control and test concreting using RAPIDOBAT shuttering tubes, as well as maintaining close communications with building sites, H-BAU has gathered positive experience with the following concrete composition: Aggregates: Sand % Gravel % Gravel % Cement kg Filler kg Water/cement ratio w/c Plasticiser Note One of the greatest uncertainty factors when using ready-made concrete is residual concrete or water remaining in the drum mixer following previous transport. The result is excess water, which leads to concrete bleeding. Practice also shows that in an attempt to prevent cavity formation on the surface of the concrete, the concrete formulation can often fall victim to overreaction. That is, the aggregate fines and the cement component are exaggerated, generally leading to a poorer result. 5 Rounded or squared, we re always prepared

18 RAPIDOBAT Application notes Transport Avoid pressure points. Do not stack pipes too high. Cover damaged outer liners generously with adhesive tape. Storage Store vertically where possible. Ensure a level, clean substrate for horizontal storage. Avoid high stresses. Keep dry. Protect from rising damp. Keep cool. Provide ventilation when covered. Preparation Adapt column reinforcement, including spacers, to suit column formwork, ensuring that the inner surface of the shuttering tube is not damaged. Remove any pools of water around the column. Concreting Place concrete using filling hose. Place concrete in 50 cm layers and compact using internal vibrator. Compact each layer and needle to underlying layer. The wall thickness of the RAPIDOBAT shuttering tubes means they are designed to withstand all the vibrations and stresses imposed by an internal vibrator. Caution: Do not vibrate externally! Stripping Strip formwork after approx. 48 h. Open shuttering tube using ripcord. Carefully cut the cover liner in the region of the ripcord using a knife. Wind the ripcord around a hammer shaft and pull vigorously. Erecting and aligning Check RAPIDOBAT shuttering tube for damage. Always erect shuttering tube with arrow pointing up. Immobilise the bottom of the shuttering tube, e.g. using a wooden annulus. Refer to Page 19. Align shuttering tube with the aid of RAPIDO-Clamp, type D, M or P. Avoid pressure points. Cover the top of the shuttering tubes with plastic sheeting until concreting begins. Open the shuttering tube and remove it. The shuttering tube can then be repositioned around the column as protection. Disposal RAPIDOBAT shuttering tubes can be disposed of in the paper recycling unit. 18

19 RAPIDOBAT Application notes for better solutions Application notes for RAPIDOBAT Cretcon HD Score the Cretcon HD coating along the former location of the ripcord using a knife to create a predetermined breaking point. Push an insulation anchor or a plastic nail also referred to as a pine cone up behind the Cretcon HD coating and pull downwards. Do not use sharp objects. Opening the Cretcon HD coating, e.g. using a plastic nail (pine cone) Securing the RAPIDOBAT shuttering tubes Up to a shuttering tube length of 5.00 m the shuttering tube can be secured using a single guy plane. Additional guy planes must be used for shuttering tube lengths greater than 5.00 m. If heavy tension-compression props are used for guying, we recommend installing additional, short pieces of shuttering tube beneath the RAPIDO- Clamp elements. This prevents pressure points on the shuttering tube and the concrete column. Lower supports The lower RAPIDOBAT shuttering tube support can be easily provided by a wooden annulus (may be cut using a template), tightly surrounding the outside of the pipe. Where larger formwork diameters are used, we recommend providing the shuttering tube with an approx. 10 cm high wooden annular base. RAPIDOFIX was specially designed for aligning the RAPIDOBAT Square and Rectangle models: simple, practical, good. Refer to Page 17.
