What is the difference between autoclaved sand-lime brick and autoclaved aerated concrete block

The raw material of autoclaved lime-sand brick is mainly sand. Promoting autoclaved lime-sand brick to replace clay brick has a positive effect on reducing environmental pollution, protecting farmland and improving building functions. The performance of autoclaved lime-sand brick is analyzed and studied, the problems existing in the application of autoclaved lime-sand brick are discussed, and the technical measures that should be taken in design and construction are put forward.

Application of jadeite powder

Fluorite for other uses is the most important fluorine-containing industrial mine. Human beings have a long history of using fluorite, which is widely used in metallurgy, chemical industry, cement industry, glass industry, ceramic industry and other fields. The processed fluorite powder is widely used in chemical industry, steel making, nonferrous metallurgy, glass and ceramics and other industries, such as military cables, optical fiber transmission and other advanced and sophisticated fields.

How to identify jadeite

Fluorite, also known as fluorite, is a mineral. Its main component is calcium fluoride (CaF2), which contains many impurities. Ca is often replaced by rare earth elements such as Y and Ce. In addition, it also contains a small amount of Fe2O3, SiO2 and trace amounts of Cl, O3, He, etc. Fluorite in nature often shows bright colors, and its hardness is lower than that of a knife.
