Carbon-reducing auxiliary agent for cement with large mixing amount of limestone and preparation method of carbon-reducing auxiliary agent
The invention discloses a large-dosage limestone cement carbon-reducing auxiliary agent and a preparation method thereof, and solves the technical problems that a small amount of cement grinding aid for improving the content and performance of limestone in cement is used, and the commercially available grinding aid cannot improve the strength of large-dosage limestone cement (the mass fraction gt of limestone is 20%) at all ages. The invention relates to a water-retaining agent comprising 7-20% of a coagulant; 0.02 to 0.4 percent of dispersing agent; 5-15% of alcohol amine, and the balance of water, wherein the total amount is 100%. The cement clinker is stable in physicochemical property, non-toxic and pollution-free, the clinker dosage can be further reduced by adding the grinding aid, the clinker is replaced by the same amount of limestone, and the strength of the cement at each age is remarkably improved.
本发明公开了一种大掺量石灰石水泥降碳助剂及制备方法，解决了提升水泥中石灰石含量和性能的水泥助磨剂较少，市售助磨剂对大掺量石灰石水泥（石灰石质量份数>20%）的各龄期强度提升不足的技术问题。它包括促凝剂：7‑20%；分散剂：0.02‑0.4%；醇胺：5‑15%，剩余部分用水补齐至100%。本发明物理化学性质稳定，无毒无污染，叠加助磨剂使用能进一步减少熟料用量并用等量石灰石代替，显著提高水泥各龄期强度。
