Crushed Rock

 · Concrete is a mixture of cement, sand, and crushed rock or stone of different varieties. In the Texas area most of the crushed rock that is utilized is crushed limestone, crushed concrete, or a smooth river rock. The hardness of the stone is very important as there is a correlation between stone hardness and strength of the finished concrete.

crush strength of sand

The Fundamentals of Frac Sand LogisticsHi-Crush Inc. API requires sand to withstand stress of 4,000–6,000 psi. Generally, smaller grains have higher crush strengths and are specified for deeper wells. Testing applies compressive strength to the sand grain. When crush strength is exceeded, the grain breaks and produces pieces, or fines.
