Regulation and control cementing material for promoting hydration of Portland cement
The invention provides a regulation and control cementing material for promoting hydration of Portland cement. The cement-based composite cementing material provided by the invention is rapid in hydration hardening and excellent in early strength. The composite cementing material is prepared from the following raw materials in parts by mass: 27 to 68 parts of anhydrous calcium sulphoaluminate, 29 to 68 parts of gypsum, 2 to 5 parts of lithium nitrite, 0.14 to 0.29 part of ethylene glycol monoisopropanolamine, 0.04 to 0.09 part of triethanolamine acetate and 0.04 to 0.09 part of polyglycerol. Through the synergistic hydration reaction of the anhydrous calcium sulphoaluminate, the gypsum and the clinker minerals and the reinforced solubilization effect of the early strength agent, the dissolution and hydration of the clinker minerals are accelerated, so that the early strength of the Portland cement is improved.
本发明提供了一种促进硅酸盐水泥水化的调控胶凝材料。本发明提供的材料水化硬化快，早期强度优异的水泥基复合胶凝材料。该复合胶凝材料包括以下质量分数配制的原料：无水硫铝酸钙：27～68份、石膏：29～68份、亚硝酸锂：2～5份、乙二醇单异丙醇胺：0.14～0.29份、三乙醇胺乙酸酯：0.04～0.09份、聚合甘油：0.04～0.09份。本发明通过无水硫铝酸钙、石膏、熟料矿物的协同水化反应、早强剂的强化增溶作用，加快各熟料矿物的溶解与水化，进而提高硅酸盐水泥的早期强度。
