At present, artificial sand has become the mainstream fine aggregate in concrete preparation.
Its use not only makes up for the shortage of river sand, but also prevents the environmental damage caused by river sand mining.
However, a large amount of stone powder is generated during the production process of artificial sand, accounting for about 4% of the total production of artificial sand.
If the stone powder is not effectively utilized, it will cause environmental pollution risks and resource waste, and floating in the air will also harm people’s health and life.
Therefore, the resource utilization of stone powder is urgent.
