Composite cement and production process thereof
The invention relates to composite cement and a production process thereof, belonging to the technical field of building materials. The composite cement comprises the following components by weight: 90-100 parts of cement clinker, 30-40 parts of mineral powder, 15-25 parts of fly ash, 6-10 parts of limestone powder, 3-7 parts of gypsum, and 0.3-0.5 part of a polymer grinding aid, wherein the polymer grinding aid is synthesized from diethanolisopropanolamine, methacrylic acid and allyl polyoxyethylene ether. The production process for the composite cement comprises the step of grinding variouscomponents according to the desired weight part ratio under the action of the polymer grinding aid so as to prepare the composite cement. The production process of the invention has the effect of goodpulverizing effect.
本发明涉及一种复合水泥及其生产工艺，属于建筑材料的技术领域，一种复合水泥，按重量份计包括以下组分：水泥熟料90‑100份，矿粉30‑40份，粉煤灰15‑25份，石灰石粉6‑10份，石膏3‑7份，高分子助磨剂0.3‑0.5份；高分子助磨剂由二乙醇单异丙醇胺、甲基丙烯酸、烯丙基聚氧乙烯醚合成的高分子助磨剂；一种复合水泥生产工艺：在高分子助磨剂的作用下将各组分按重量份进行粉磨，制得复合水泥。本发明具有粉磨效果好的效果。
