Abstract
The invention discloses a preparation method of sulfate corrosion resistance cement, which comprises the steps of adding waste, namely stainless steel slag, resulting in heavier and heavier loads and produced by the steel industry to ordinary portland cement, roasting into portland cement clinker at the superhigh temperature, treating solid waste residue, namely phosphogypsum, produced by treating phosphorite with sulfuric acid during phosphoric acid production to a certain extent, and then replacing ordinary gypsum with the phosphogypsum to fabricate the sulfate corrosion resistance cement together with the portland cement clinker. On the one hand, the problems of environment pollution and appropriation of land due to waste stacking are solved. On the other hand, the waste is recycled, the cement production cost is lowered, the sulfate corrosion resistance of the sulfate corrosion resistance cement finish product is effectively improved; and application prospects of environmental, social and economic benefits are realized.
