Energy-efficient Sand promote a smooth transition in the field of cement and other construction workers

With the increasing depletion of non-renewable resources, energy saving and environmental protection issues to regain the attention of the accelerated pace of urbanization, increasing demand for sand and gravel, river sand mining resources such uncontrolled sharply, severely damaged the ecological environment of the river, for the protection of the riverbed, they have introduced a comprehensive policy restrictions around river sand mining, encourage enterprises to adopt artificial sand instead of natural sand. According to experts, due to the mining limits, the high price of natural sand, which is very serious depletion of natural sand as non-renewable resources, can not meet the needs of our current sand, and sand as an ideal alternative to natural river sand, will become the next major source of sand, sand industry has been a new development opportunities.

From the strict requirements in terms of engineering and construction, partially due to mixing sand powder, used in cement, construction and other areas of more than natural sand advantage, in addition, according to the national standard GB / T1468 "building sand" revision adds artificial system sand for construction of sand to determine the definition of artificial sand, technical requirements, test methods.
