When configuring concrete, coarse and medium river sand should be preferred for fine aggregate. The fineness modulus of desert sand is usually less than 1.5, and the finer one has a modulus less than 0.7, which is ultra-fine sand. Concrete that uses desert sand alone will consume a large amount of cement, reduce strength, and weaken frost
