Improving environmental quality, promoting green development, building a conservation oriented society, and promoting clean and civilized production are the themes of today’s social development.
The comprehensive utilization of resources and the construction of a circular economy are fundamental to the sustainable development of enterprises.
China’s construction projects cannot do without cement concrete, which is mainly made of cement, stones, and natural river sand.
Natural sand is a non renewable resource, and many places have taken measures to restrict or ban its use due to environmental protection.
With the increasing protection of the environment, the contradiction between using sand as a commodity concrete mixing plant for concrete production has become increasingly prominent.
The quality of natural sand has been declining year by year and is seriously in short supply.
The price of sand continues to rise, and during the peak period of concrete consumption, there is even no sand available, which affects the development of engineering construction.
Therefore, in response to environmental protection requirements and industry demands, it is necessary to explore a material that can replace or partially replace natural sand, which can not only save production costs but also use local materials to protect local environmental resources.
