Sulfate-corrosion-resistant waterproof mortar and preparation method thereof
The invention discloses sulfate-corrosion-resistant waterproof mortar and a preparation method thereof. Comprising the following raw materials in parts by weight: 250-350 parts of nickel slag, 20-30 parts of carbide slag, 25-35 parts of sodium carbonate, 4-6 parts of basalt fiber, 5-7 parts of sodium lignin sulfonate, 40-50 parts of polyvinyl alcohol stabilized ethylene-vinyl acetate emulsion, 750-1050 parts of ferronickel tailings, 35-45 parts of water, 4-6 parts of an auxiliary agent, 1-6 parts of a water reducing agent and 1-2 parts of a defoaming agent. According to the sulfate-erosion-resistant waterproof mortar prepared by adopting a wet-grinding ultrafine mode and the preparation method, sulfate erosion of concrete can be effectively prevented, the mortar has excellent self-repairability and impermeability, coordination of body deformation is guaranteed, the materials are low in cost, easy to obtain and environmentally friendly, the operation process is simple and convenient, the preparation cost is effectively reduced, and the method is suitable for industrial production. And the method has obvious practicability and economical efficiency.
本发明公开了一种抗硫酸盐侵蚀防水砂浆及制备方法，包括如下重量份的原料：镍渣250‑350份、电石渣20‑30份、碳酸钠25‑35份、玄武岩纤维4‑6份、木质素磺酸钠5‑7份、聚乙烯醇稳定的乙烯‑醋酸乙烯乳液40‑50份、镍铁尾矿750‑1050份、水35‑45份、助剂4‑6份、减水剂1‑6份、消泡剂1‑2份。本发明采用湿磨超细化方式制得的抗硫酸盐侵蚀防水砂浆及制备方法可有效阻止混凝土硫酸盐侵蚀，具有优异的自修复性和抗渗性，保证机体变形相协调，材料价廉易得，绿色环保，操作工艺简单方便，有效降低制备成本，具有明显的实用性和经济性。
