Quick-hardening high-corrosion-resistance mortar repairing material for sewage concrete structure
The invention discloses a quick-hardening high-corrosion-resistance mortar repairing material for a sewage concrete structure. The quick-hardening high-corrosion-resistance mortar repairing material is composed of the following components in percentage by weight: 61%-70% of ordinary Portland cement, 2%-5% of sulphoaluminate cement, 8%-10% of fly ash, 2%-5% of silica fume, 2%-5% of gypsum, 4%-7% of an expanding agent, 0.5%-1% of a water reducing agent, 2%-6% of latex powder and 0.1%-0.2% of ethanolamine. The corrosion resistance coefficient of the quick-hardening high-corrosion-resistance mortar repairing material reaches 1.2, the tensile adhesive strength reaches 1.7 MPa, the 28 d compressive strength reaches 48 MPa or above, and an acid corrosion soaking 180 d test proves that the material has high weak acid corrosion resistance, meets the requirement of high corrosion resistance of sewage concrete structures, can be used as an effective anti-corrosion concrete coating layer, and is of great significance to long-term safe operation of sewage treatment facilities.
本发明公开了一种污水混凝土构筑物快硬型高耐腐蚀砂浆修补材料，由以下重量百分比的组分组成：61％‑70％的普通硅酸盐水泥、2％～5％硫铝酸盐水泥、8％～10％的粉煤灰、2％～5％的硅灰、2％～5％的石膏、4％～7％的膨胀剂、0.5％～1％的减水剂、2％～6％的乳胶粉以及0.1％～0.2％的乙醇胺；该快硬型高耐腐蚀砂浆修补材料的抗蚀系数达到1.2、拉伸粘结强度达到1.7MPa，28d抗压强度达到48MPa以上，并且经酸腐蚀浸泡180d试验验证，该材料具有较高的耐弱酸腐蚀作用，满足了污水混凝土构筑物高耐腐蚀性的要求，作为一种有效的防腐混凝土涂层，对污水处理设施的长期安全运营具有重要的意义。
