Characterization of a self-compacting sand concrete using the quarry waste

Self-compacting sand concrete (SCSC) can be made by using the quarry waste, thus helping to reduce the actual deficit in aggregates in Algeria and contribute to the solution of an acute environmental problem. The SCSC presented in this paper is made with aggregates whose maximum size is less than 5 mm. Several mixes were prepared by varying parameters, such as water volume, weight and nature of cement, weight of sand, nature of admixtures, and shape of aggregates. Each one of the SCSC mixes has been analyzed by considering its rheological behavior in the fresh state and its mechanical behavior in the hardened state. In the fresh state, the elaborated SCSC satisfies the recommendations of the Association Française de Génie Civil (AFGC) and in the hardened state, its mechanical performance is good.
