Crushed sand particle though shaped, does not have the spherical shape of natural sand. Hence the crushed sand will have greater water demand than that of natural sand resulting in slightly higher cement consumption. However, if crushed sand is properly graded with adequate fines the mix may have lower water demand when compared to poorly ...

Add gravel or crushed stone to the dry mixture to a ratio of as much as 5 parts gravel to 1 part cement and sand mixture. The gravel doesn't effect the tensile strength of the concrete unless you add so much there isn't enough cement paste to fill the voids in the finished concrete, it merely acts as a filler, taking up space.
