Recently, a new childcare facility was built in a residential area in the town of Savigny-sur-Orge south of Paris, France. A large new building was constructed facing the street. The precast concrete elements were produced directly on the jobsite.
Plastic cones were used as spacers for setting the precast formwork. Following the production of the precast elements, the voids left by the spacers were filled using concrete cones. To create a waterproof bond between the concrete cone and the precast element, Ravalchoc® Flexible Etanche was used. It offers exceptional bond strength and high mechanical strength. Finally, for the precast elements produced on the jobsite, a special anchoring system has been used.
In this project, a new mould release agent conforms to the new Classification Synad (the French professional admixtures association) for such requirements as biodegradability, for example. This product has also been developed in order to comply with the CLP Regulation (Classification, Labelling and Packaging).The special product releases all the precast beams from the mould easily and simultaneously creates a high quality concrete surface.
