Low-carbon cementing material
The invention discloses a low-carbon cementing material which comprises the following components in percentage by mass: 30%-40% of Portland cement clinker, 10%-15% of limestone powder, 20%-25% of uncalcined alunite, 15%-20% of zeolite powder, 5%-15% of anhydrite and 1%-3% of a flow state improving material. In the working process, the use amount of Portland cement clinker is reduced, and carbon reduction is facilitated. Meanwhile, the alunite is not calcined, so that the use of fossil energy is reduced in the preparation process, and carbon is effectively reduced. The anhydrite is adopted, so that the activity of the uncalcined alunite is remarkably improved, and the reaction rate of the uncalcined alunite is effectively increased. The flow state improvement material is utilized to improve the rheological property and the mechanical property of the low-carbon cementing material system under the conditions of reducing the cement consumption and improving the alternative cementing material, so that the components have better compatibility.
本发明公开了一种低碳胶凝材料，所述胶凝材料按质量百分比计包括：硅酸盐水泥熟料30%~40%，石灰石粉10%‑15%，未煅烧明矾石20%~25%，沸石粉15%~20%，硬石膏5%~15%，流态改善材料1%~3%。本发明在工作中，减少了硅酸盐水泥熟料用量，有利于降碳。同时，明矾石为未煅烧，这样，在配制过程中减少化石能源的使用，有效减碳。采用硬石膏，显著改善了未煅烧明矾石的活性，有效提高了未煅烧明矾石的反应速率。利用流态改善材料，在降低水泥用量、提高替代性胶凝材料的条件下，改善了低碳胶凝材料体系的流变性能及力学性能，使得各组分之间具有更良好的相容性。
