Grinding aid for improving adaptability of high-aluminum clinker cement admixture
The invention discloses a grinding aid for improving the adaptability of a high-alumina clinker cement admixture, and solves the technical problems that a grinding aid in the prior art causes lowadaptability of high-alumina clinker cement to the admixture and reduces the early strength of the high-alumina clinker cement. The grinding aid comprises: 3%-20% of dimer glycerol; 10%-27% of monoethanol diisopropanolamine; 2%-7% of hydroxyethylidene diphosphonic acid; 0.1%-0.25% of polyacrylamide; and the balance of water. Compared with a traditional grinding aid, the grinding aid for improving the adaptability of the high-aluminum clinker cement admixture has higher admixture adaptability, the fluidity of neat paste is improved by 20 mm or above, the slump of C30 and C25 concrete is improved by 15 mm or above, and the expansion degree is improved by 15 mm or above; and the formula of the grinding aid is optimized to improve the 28-day strength of the high-alumina clinker cement concrete.
本发明公开了一种提高高铝熟料水泥外加剂适应性的助磨剂，解决了现有技术中的助磨剂使高铝熟料水泥与外加剂适应性变差、使高铝熟料水泥的早期强度降低的技术问题。它包括二聚丙三醇：3%‑20%；一乙醇二异丙醇胺：10%‑27%；羟基乙叉二膦酸：2%‑7%；聚丙烯酰胺：0.1%‑0.25%；水：余量。本发明中提供的提高高铝熟料水泥外加剂适应性的助磨剂，与传统助磨剂相比，不仅具有更好的外加剂适应性，使净浆流动度提高20mm以上，C30、C25混凝土塌落度提高15mm以上，扩展度提高15mm以上；而且助磨剂配方的优化对高铝熟料水泥的混凝土28天强度也有提高作用。
