Powdery cement grinding aid for promoting cement grinding
The invention discloses a powdery cement grinding aid for promoting cement grinding, which is characterized by being mainly prepared from the following raw materials: methyl dodecyl aminopropionate, montmorillonite, nano silicon dioxide, medium-calcium fly ash and an additive, the preparation method of the medium-calcium fly ash comprises the following steps: uniformly mixing calcium carbonate, calcium chloride and fly ash, and calcining at 1300-1500 DEG C for a period of time to obtain the medium-calcium fly ash. According to the powdery cement grinding aid for promoting cement grinding, all the raw material components play a synergistic and complementary role, the grinding effect and the grinding speed of cement in the grinding process are improved, the energy consumption of a ball mill is reduced, and the cement grinding cost is reduced. Meanwhile, cement prepared from the powdery cement grinding aid is good in compressive strength and cracking resistance.
本发明公开了一种用于促进水泥粉磨的粉状水泥助磨剂，其特征在于，主要有以下原料制成：十二烷基氨基丙酸甲酯、蒙脱石、纳米二氧化硅、中钙粉煤灰、添加剂；所述中钙粉煤灰制备方法如下：将碳酸钙、氯化钙与粉煤灰混匀后于1300‑1500℃温度条件下煅烧一段时间，得到中钙粉煤灰。本发明用于促进水泥粉磨的粉状水泥助磨剂，各原料组份发挥协同互补作用，提高水泥在粉磨过程中的粉磨效果和粉磨速率，减少球磨机耗能，降低水泥粉磨成本。同时用该粉状水泥助磨剂制备获得的水泥的抗压强度和抗开裂性能好。
