There quicklime and slaked lime (ie lime), its magnesium oxide content (5% threshold) can be divided into calcium lime and magnesia lime. Because of its wide distribution of raw materials, production process is simple and low cost. Lime has a strong alkaline lime, building lime at room temperature, it can react with the active silica or alumina glassy activity, have generated a product of the industrial use of hydraulic lime to produce cement. Therefore, lime is an important raw material in the building materials industry. Lime white or gray lump quicklime calcium oxide, for ease of use, which require massive lime powder processed into quicklime, slaked lime powder or paste. Quicklime lump lime powder is obtained by grinding powder, the main ingredient is CaO. Lime Scope: a lot of lime and limestone used as building materials, is an important raw material in many industries.
