Grinding aid for improving early strength of Portland cement
The invention discloses a grinding aid for improving early strength of Portland cement. The grinding aid comprises the following raw materials in parts by weight: 10-30 parts of an alcohol amine compound, 5-20 parts of polyol, 0.1-3 part of sodium gluconate, 0.1-3 part of a modified water reducing agent, 0.5-2 part of sodium hexametaphosphate, 0.5-3 part of tartaric acid, 0.3-3 part of sugar calcium, 0.3-1.5 part of a modified dispersing agent and 20-100 parts of water. The grinding aid disclosed by the invention is added into Portland cement and has a good grinding aid effect on the cement, the granularity of a cement grinding material is obviously reduced, the specific surface area is increased, and the early strength of the Portland cement is further enhanced.
本发明公开了一种提高硅酸盐水泥早期强度的助磨剂，其包含以下重量份的原料：醇胺类化合物10‑30份、多元醇5‑20份、葡萄糖酸钠0.1‑3份、改性减水剂0.1‑3份、六偏磷酸钠0.5‑2份、酒石酸0.5‑3份、糖钙0.3‑3份、改性分散剂0.3‑1.5份、水20‑100份。将本发明的助磨剂添加到硅酸盐水泥中，对水泥有良好的助磨效果，明显降低水泥磨料的粒度，增加比表面积，进而增强硅酸盐水泥的早期强度。
