Waterproof and anti-permeability repair mortar as well as construction method and application
The invention belongs to the field of building materials, and relates to a waterproof anti-impermeability repair mortar, and a construction method and applications thereof. The repair mortar comprisesthe following raw materials by weight: 20-30% of sulphoaluminate cement, 1-5% of fly ash, 0.5-3% of silica fume, 0.1-0.5% of polyvinyl alcohol rubber powder, 0.1-0.3% of a water reducer, 0.05-0.2% ofan antifoaming agent, 0.05-0.2% of a retarder, 10-15% of water, and 60-70% of river sand. The bonding tensile strength of the repair mortar is 2-5MPa, and the impermeable pressure exceeds 4MPa. The repair mortar is excellent in performance, convenient to construct, low in cost, green and environment-friendly.
本发明属于建筑材料领域，涉及一种防水抗渗修补砂浆及施工方法与应用，所述修补砂浆按照重量百分比的原料为：硫铝酸盐水泥20‑30％，粉煤灰1‑5％，硅灰0.5‑3％，聚乙烯醇胶粉0.1‑0.5％，减水剂0.1‑0.3％，消泡剂0.05‑0.2％，缓凝剂0.05‑0.2％，水10‑15％，河砂60‑70％。本发明的修补砂浆黏接抗拉强度为2‑5MPa，抗渗压力超过4MPa。本修补砂浆性能优异，施工便利，成本低廉，绿色环保。
