If we design the concrete proportion according to the characteristics of the artificial sand, and adjust the sand ratio of the artificial sand by reasonably using the stone powder in the artificial sand, we can make the concrete with good workability. The mix design method of the common concrete mix design specification is completely applicable to the artificial sand. The fineness modulus of artificial sand is 2.6-3.0, and the gradation is 2 zones. The reaction of artificial sand to admixture is more sensitive than that of natural sand. Artificial sand is especially suitable for the preparation of high-strength concrete, high-performance concrete and pumping concrete.
