Low-activity pozzolanic admixture cement carbon-reducing auxiliary agent and preparation method thereof
The invention discloses a low-activity pozzolanic admixture cement carbon-reducing auxiliary agent and a preparation method thereof, and solves the technical problems that the cement preparation process is limited by the mixing amount of a cement grinding aid, and the strengthening effect on cement is poor due to excessive effective components such as alcohol amine and alcohol. The coating comprises the following components: 3-15% of nano calcium carbonate; 0.02 to 0.4 percent of dispersing agent; 10-20% of alcohol amine, and the balance of water, wherein the total amount is 100%. The cement grinding aid is stable in physicochemical property, free of toxicity and pollution, free of chloride ions and friendly to equipment, the use amount of clinker can be further reduced by adding the grinding aid, the clinker is replaced by an equivalent low-activity pozzolanic admixture, and the strength of cement in each age is remarkably improved.
本发明公开了一种低活性火山灰质混合材水泥降碳助剂及制备方法，解决了水泥制备过程中受限于水泥助磨剂掺量，其有效组分醇胺、醇类过量对水泥提强作用不佳的技术问题。它包括纳米碳酸钙：3‑15%；分散剂：0.02‑0.4%；醇胺：10‑20%，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，不含氯离子对设备友好，叠加助磨剂使用能进一步减少熟料用量并用等量低活性火山灰质混合材代替，显著提高水泥各龄期强度。
