Calcium oxide mainly from calcareous material Wuhan cement tile, such as limestone, chalk, marl and the like; aluminum oxide and silicon oxide is derived from substances containing aluminum silicate wholesale Wuhan cement, such as clays, blast furnace slag, fly ash; the use of sulfuric acid in the production of iron pyrite slag. For the production of portland cement calcareous material content of calcium oxide is generally about 52%; clayey raw material silicon oxide content of about 57% of Wuhan cement, aluminum oxide content is less than 20%. Sometimes sulfates, titanates, etc., but fewer. Since clinker also contain other oxides, each of the above compounds are not in a pure state, that often have a variety of other oxide solution. So turn them in mineral phases (ie, crystalline) to name, such as tricalcium silicate Alit said, which accounts for more than 50% in the clinker; dicalcium said belite, contains about 25 percent; aluminate three calcium aluminate; almandine four calcium before Bartlett said.
