Novel cement grinding aid
The invention belongs to the field of cement admixtures, and relates to a novel cement grinding aid. The novel cement grinding aid is prepared from the following components: 15 to 30 parts of alcohol amine compound, 10 to 20 parts of hydroxypropyl methylcellulose titanate, 20 to 40 parts of modified phosphogypsum, 5 to 15 parts of sodium lignin sulfonate and 3 to 10 parts of calcium nitrate. By utilizing the novel cement grinding aid provided by the invention, the machine-hour yield of a mill and the cement compressive strength can be remarkably improved, the 45-micron-fineness screen residue and the setting time are reduced, and the effect is remarkable.
本发明属于水泥外加剂领域，涉及一种新型水泥助磨剂。本发明所述新型水泥助磨剂，由以下成分组成：醇胺类化合物15‑30份、羟丙甲纤维素钛酸酯10‑20份、改性磷石膏20‑40份、木质素磺酸钠5‑15份、硝酸钙3‑10份。利用本发明所提供的新型水泥助磨剂可显著提高磨机台时产量、水泥抗压强度，降低45μm细度筛余、凝结时间，效果显著。
