The invention discloses a silicate concrete corrosion resistance additive which is characterized by being prepared from the following components in parts by mass: 10-15 parts of rice hull ash, 20-30 parts of volcanic ash, 5-8 parts of tetramethoxysilane, 5-8 parts of a functional nano material, 5-8 parts of 3-(triethoxysilyl) propyl methacrylate, 3-5 parts of itaconic acid, 20-30 parts of calciumsulfate, 5-10 parts of polycarboxylate and 3-5 parts of a composite water reducing agent. The invention also provides a preparation method of the silicate concrete corrosion resistance additive. The corrosion resistance additive prepared by the method can effectively improve the corrosion effect of silicate concrete on acid, alkali and solvent and can prolong the service life of silicate concretein acid, alkali and other severe environments.
一种硅酸盐混凝土防腐性能添加剂，其特征在于由以下质量配比的成分组成：稻壳灰10‑15份、火山灰20‑30份、四甲氧基硅烷5‑8份、功能纳米材料5‑8份、3‑(三乙氧基甲硅烷基)丙基甲基丙烯酸酯5‑8份、衣康酸3‑5份、硫酸钙20‑30份、聚羧酸脂5‑10份、复合减水剂3‑5份。本发明还提供了一种硅酸盐混凝土防腐性能添加剂的制备方法，经本发明制备的防腐剂可以有效的提高硅酸盐混凝土对酸、碱和溶剂的腐蚀效果，可以提高硅酸盐混凝土在酸性和碱性等恶劣环境中的使用寿命。
