Abstract: In order to better understand self-compacting concretes and to facilitate their industrial development, a French national project has been created (PN B@P in French). This project involved 50 different partners from building industry and public works, and its total budget was around 4 242 000€. All partners of the PN B@P have shared their knowledge to develop tools for production follow-up, quality control, tests on jobsite and to give advice for the building contract. Moreover, this work had to take into account European projects that were in progress. Among all questions to which this national project had to answer, one of the main queries was to know if SCC could respect the same current standards (for example EN 1992-1-1, future NF EN 13670-1, etc.) than conventionally-vibrated concrete, or if we had to adapt them. From the production to durability of hardened SCC without forgetting transport, placing, cure, facing, adhesion to reinforcement, construction joint, shrinkage, sensitivity to cracking, different modulus, all researches have been completed by different task groups.
After technical studies, only social and economic SCC impacts were missing. Now, all information necessary to a good use of SCC on building sites or in pre-cast plants is available in France.
