Artificial sand is superior to ordinary natural sand in all aspects due to its own characteristics. The degree of sand thickness refers to the average thickness that mixed together with different grain granularity. Normally it is divided into coarse sand, medium sand and fine sand. The grain grading is the matching proportion of different sand size. The sand with good grading can not only save the concrete, but also improve the compactness and strength of concrete and mortar.
