Influence of Local Sand on the Physicomechanical Comportment and ...

The partial replacement of natural sand (SD) by crushed sand (1/3, 2/3 of CS combined) results in increasing compressive strengths of the concrete HPC (1/3 SD) and HPC (2/3 SD) compared to the concrete HPC (SD). The use of manufacture sand increases the mechanical strength of the concrete, depending on the percentage of crushed sand used.
