Aluminate Cement CA-40-Fused

CA-40-Fused high iron aluminate cement is made of high iron bauxite and limestone of high quality through smelting in electric furnace, cooling and then grinding. It possesses the properties of early strength, free from free calcium oxide, weatherproof and chemical erosion-proof. It is commonly used in chemical construction together with portland cement.
