Low-calcium Portland cement clinker, cement and preparation method
The invention discloses a low-calcium Portland cement clinker, cement and a preparation method, and the cement clinker comprises the following mineral components in percentage by mass: 5 to 20 percent of C3S, 50 to 60 percent of C2S, 10 to 20 percent of C6AF2, 0 to 7 percent of C3A and 0.1 to 15 percent of C4A3. By designing the high silicon content, the C2S content in the cement clinker is improved, the later performance of the clinker is further improved, meanwhile, the problem that the early hydration activity of the clinker is insufficient due to the fact that the C2S content is improved is solved through early strength formed by rapid hydration of C4A3, and cement has good performance development in the early stage, the middle stage and the later stage.
本发明公开了一种低钙硅酸盐水泥熟料、水泥及制备方法，所述水泥熟料以质量百分数计，包括以下矿物组分：C3S:5~20%，C2S:50~60%，C6AF2:10~20%，C3A:0‑7%，C4A3$:0.1~15%。本发明通过设计高硅含量，提高水泥熟料中C2S含量，进而提升熟料后期性能，同时，C4A3$快速水化形成的早期强度将弥补C2S含量提高带来的熟料早期水化活性不足的问题，使水泥早中后期均有良好的性能发展。
