As the ratio of artificial sand increases, the external shrinkage volume increases. The shrinkage occurs on the top surface, and the central part is the deepest. The 1 cm 3 of shrinkage volume is about 0.006% of the test piece shape. For example, in the case of artificial sand, the shrinkage volume of 140 cm 3 is 0.8

The fineness modulus of sand used in ordinary concrete is 3.7-1.6, medium sand is suitable, and coarse sand plus a small amount of fine sand can also be used, and the ratio is 4 to 1. For natural sand, one fineness modulus can have multiple gradations. For artificial sand, one fineness modulus corresponds to only one gradation.

The most common type of sand used as infill for artificial grass is silica sand. It differs from normal sharp /regular sand in that it is at least 95% silicon dioxide. This results in a finer granule that has more rounded edges. You can purchase silica sand that is specifically for use with artificial turf.
