Quick-repair cement mortar and preparation method thereof
The invention relates to a quick-repair cement mortar and a preparation method thereof, and relates to the field of environment-friendly quick-repair cement mortars.The quick-repair cement mortar is prepared from, by weight, 30-35 parts of magnesium phosphate cement, 15-20 parts of Portland cement, 37.5-42.5 parts of fly ash, 32.5-37.5 parts of steel slag powder, 90-100 parts of quartz sand, 1-1.5 parts of an active exciting agent, 0.25-0.75 part of a reinforcing agent, 0.25-0.3 part of a thickening agent, 0.25-0.4 part of a water reducing agent and 66-77 parts of water; the active exciting agent comprises water glass, anhydrous sodium sulphate, sodium hydroxide and a modified polymeric dispersant in a weight ratio of (8-10): (5-7): (5-7): (15-20). The method has the advantages that the mixing amount of the industrial waste residues is increased, the utilization rate of the industrial waste residues is increased, and the quick-repair cement mortar has high strength.
本申请涉及一种快修水泥砂浆及其制备方法，涉及环保型快修水泥砂浆的领域，其包括以下重量份的组分：磷酸镁水泥30‑35份、硅酸盐水泥15‑20份、粉煤灰37.5‑42.5份、钢渣粉32.5‑37.5份、石英砂90‑100份、活性激发剂1‑1.5份、增强剂0.25‑0.75份、增稠剂0.25‑0.3份、减水剂0.25‑0.4份和水66‑77份；活性激发剂包括重量比为（8‑10）:（5‑7）:（5‑7）:（15‑20）的水玻璃、元明粉、氢氧化钠和改性高分子分散剂。本申请具有增加工业废渣的掺量，提高工业废渣利用率并使得快修水泥砂浆具有较高强度的效果。
