Correlation Between Materials Finer Than No. 200

Also, the effects of silica and crushed sands (using different values of sand equivalent and passing No. 200 sieve) on water demands of mortar were investigated. A strong correlation was found between the sand equivalent and fine materials passing No. 200 for silica sand, whereas there was no correlation for the crushed sand.

Influence of Local Sand on the Physicomechanical

This research consists of incorporating the crushed sand (CS) in the composition of a concrete and studies the effect of its gradual replacement by the sand dune (SD) on sustainability of high performance concrete (HPC) in aggressive environments. The experimental study shows that the parameters of workability of HPC are improved when the CS is partially replaced by the SD (<2/3).
