铸石粉，又名辉绿岩粉。是以生产铸石优异的原料----辉绿岩为主要原料，将结晶好的铸石经破碎、球磨而制成的。具有优异的耐酸碱性能。呈淡灰色粉状细粉，主要成分是二氧化硅和氧化铝，并含有少量其它氧化物和氧化铁、氧化钙、二氧化钛等。铸石粉可以配制成耐酸（碱）胶泥，耐腐蚀性能是耐酸水泥的10倍以上。
The cast stone powder, also known as the diabase powder. The production of crystallized cast stones is made by crushing and milling with the excellent raw material, diabase as the main raw material. It has excellent acid and alkali resistance. It is a pale gray powdery fine powder, mainly composed of silica and alumina, and contains a small amount of other oxides and iron oxide, calcium oxide, titanium dioxide and so on. The cast stone powder can be made into acid resistant (alkali) cement, and its corrosion resistance is more than 10 times that of acid proof cement.
它与铸石砂，铸石骨料混合可捣固成腐蚀或耐磨混凝土，应用效果特佳。制成的一种晶粒细微、致密的非金属工业材料。
It can be mixed with cast stone sand and cast stone aggregate to form corrosive or wear-resistant concrete. It is a kind of non-metallic industrial material with fine grain density.
