Quality Testing of Sand at The Construction Site for The Concrete. There are different methods for testing the quality of sand at the construction site for concrete construction. The quality of the sand is as important as other materials for concrete. The most different, which passes through the 4.75 mm IS strainer, is known as the fine aggregate.

There are two reasons for the sometimes high price for natural sand compared to crushed aggregate: First, a good quality sand can have a huge impact on the cement consumption (the highest share of concrete self-price) needed to produce concrete with desired properties; second, the availability of good natural resources is almost exhausted in many parts of the world. This turns the spotlight on

The results of mix design indicate that crushed sand can also make as good a concrete as that made of natural sand.The compressive strength obtained is same as of normal mixes.In fact use of crushed sand will become inevitable in near future because of dwindling sources of natural sand. Crushed sand particle though shaped, does not have the spherical shape of natural sand. Hence the crushed
