As the main material in construction engineering, the annual consumption of

concrete in China is about several billion tons. The consumption of cement, sand and other raw materials every year is also very huge, resulting in a large number of high-quality sand and stone has been consumed, and the storage is less and less. But now the sand used in concrete contains more mud, which seriously affects the performance of concrete, resulting in the deterioration of concrete workability, the increase of slump loss over time, and the deterioration of volume stability and durability

The mud in

concrete generally comes from coarse aggregate and fine aggregate. According to the standard jgj52-2006 \
