Production method of low-clinker low-hydration-heat high-grade cement
The invention discloses a production method of low-clinker low-hydration-heat high-grade cement. The cement comprises the following components in percentage by mass: 45% of clinker powder and 55% of slag composite powder, and the clinker powder comprises the following components in percentage by mass: 88% of clinker, 6% of stone powder and 6% of desulfurized gypsum. The low-clinker low-hydration-heat high-grade cement is prepared by adopting a production method of respectively grinding and then blending, the quality grade completely reaches the standard of 52.5 cement specified by the nationalstandard, the hydration heat is low, and the later strength is high and is continuously increased. Compared with the grade of 52.5 cement produced by a traditional method, the use amount of clinker can be saved by at least 40%, the production cost is reduced, and a large amount of waste slag, namely blast furnace slag, generated during steel smelting is used, so that the method has important significance in improving the economic benefit, comprehensively utilizing resources, protecting the environment and building a conservation-minded society.
一种少熟料低水化热的高等级水泥的生产方法，包括质量百分比为熟料粉45％以及矿渣复合粉55％，所述熟料粉按照质量百分比包括熟料88％、石粉6％以及脱硫石膏6％，本发明采用分别粉磨再勾兑的生产方法制成少熟料低水化热的高等级水泥，质量等级完全达到国家标准规定的52.5水泥的标准，并且水化热低、后期强度高且不断增长。与传统方法生产的52.5水泥等级相比较，熟料用量可以节约至少40％，不但降低了生产成本，而且大量使用了冶炼钢铁时产生的废渣——高炉矿渣，这对提高经济效益、资源综合利用、保护环境、建设节约性社会具有重要意义。
