Road silicate cement clinker and preparation method thereof
The invention relates to road silicate cement clinker and a preparation method thereof. The preparation method for the road silicate cement clinker comprises the following steps: grinding and roasting a cement raw material, wherein the cement raw material consists of the following substances in parts by weight: 50-85 parts of lime stones, 5-20 parts of steel slag powder, 5-15 parts of sandstones and 5-15 parts of coal ash. The preparation method can be used for recycling the steel slag, grinding the steel slag into powder after drying, and adopting the prepared steel slag powder as a cement production raw material to prepare road silicate cement clinker with low heat and high fracture resistance, so that the sintering quality of the clinker can be effectively improved after the steel slag powder is added. On the basis of meeting the technical requirements specified in the road silicate cement national standards, the road silicate cement clinker can be used for improving the fracture resistance and wear resistance of the cement, and lowering the hydration heat evolution and the dry shrinkage rate.
