| titleOfInvention | Preparation method of high corrosion-resistant portland cement |
| abstract | The invention provides a preparation method of high corrosion resistant portland cement, belonging to the technical field of inorganic materials, and the preparation method comprises the following steps of grinding portland cement clinker, fly ash, cementing material and gypsum separately or jointly, and then grinding the mixture to obtain the high corrosion resistant portland cement, wherein the preparation method of the used portland cement clinker comprises the following steps: drying, mixing and grinding the clay raw material, the calcium raw material and the iron raw material to obtain a raw material; sintering the raw material and the mineralizer, and cooling to obtain portland cement clinker; wherein a mineralising agent comprising perlite and antimony trioxide is added to the raw meal powder before or during sintering. The preparation method of the portland cement clinker can improve the easy burning property of the portland cement clinker, increase the crystallinity of the clinker and improve the bending strength and the compressive strength of the clinker at different ages; the high corrosion resistant Portland cement prepared by the invention has good working performance, higher compressive strength, higher corrosion resistance and good durability. |
