Recycled concrete aggregates (RCA) contain, due to their origin, residual cement paste which gives them high porosity and moderate performance. The porosity leads to a strong water absorption. This is a major difficulty on the industrial level because it complicates the adjustment of water in concrete batches, which allows to control their workability in production. The RCA manufacturing process results in having more paste in the finer particles and therefore more absorption. As a result, while the industry today recycles coarse RCA into concrete relatively well, it uses small amounts of RCA sand because of their greater porosity. Yet, during the manufacture of RCA, about 50% sand and 50% coarse aggregates are obtained. Consequently, the p...
