Grinding aid suitable for cement with high content of limestone and preparation method of grinding aid
The invention discloses a grinding aid suitable for high-volume limestone cement, and also discloses a preparation method of the grinding aid suitable for high-volume limestone cement. The grinding aid comprises the following raw materials: 10-20% of trialkanolamine, 2-10% of sulfonate, 2-10% of phosphate, 5-10% of polyol, 5-10% of acrylamide, 8-15% of saccharides and the balance of deionized water. According to the grinding aid prepared by the invention, through the synergistic effect of active groups contained in various raw materials, the dispersing performance of cement particles with high content of limestone is improved, the later strength of cement is also improved, and the phenomenon that the cement cracks is reduced.
本发明公开了一种适用于高掺量石灰石水泥的助磨剂，还公开了一种适用于高掺量石灰石水泥的助磨剂的制备方法。所述助磨剂的原料包括：10‑20％三链烷醇胺、2‑10％磺酸盐、2‑10％磷酸盐、5‑10％多元醇、5‑10％丙烯酰胺、8‑15％糖类、去离子水补充余量。本发明制备的助磨剂，通过各种原料含有的活性基团之间的协同作用，提高了高掺量石灰石水泥颗粒的分散性能，还提高了提高水泥的后期强度，减少了水泥出现裂缝的现象。
