The invention provides high-performance environment-friendly cement and a production method thereof. The cement comprises the following raw materials in percentage by weight: 0-50% of Portland cement clinker, 45-85% of admixture, 5-15% of gypsum and 0.0-0.6% of polycarboxylic acid high-efficiency water-reducing grinding aid (solid content). The particle size of the cement clinker, the gypsum and a part of the mixed materials is smaller than (D97 = 20 microns), and the particle size of the other part of the mixed materials is smaller than (D97 = 20 microns), and the standard fluidity saturation point water demand ratio of the cement mortar is less than 0.3. Compared with the traditional method, the method provided by the invention has the advantages that the cement product and the manufacturing process are improved; the influence of chemical performance, mud, clinker mineral composition and burning on the cement performance is changed into the influence of physical performance, water, mixed material property and grinding on the cement performance. The invention provides the effective high-performance environment-friendly cement and the production method thereof.
本发明提供一种高性能环保水泥及生产方法，所述水泥原料按硅酸盐水泥熟料0%—50%，混合材45%—85%、石膏5%—15%、聚羧酸高效减水助磨剂（固体含量）0.0%—0.6%组成，水泥熟料、石膏、部分混合材粒径小于（D97=60微米），部分混合材粒径小于（D97=20微米），水泥胶砂标准流动度饱合点需水量比小于0.3。本发明颠覆性的采用迥异于传统方法对水泥产品和制造过程提出改进，从重视研究“化学性能”、“泥”、“熟料矿物组成”、“烧”对水泥性能的影响改变为重视研究“物理性能”、“水”、“混合材材性”、“磨”对水泥性能的影响，提出了一种行之有效的高性能环保水泥及生产方法。
