一种混凝土制品表面裂纹化学防腐修补材料及制备方法与施工方法
摘要：
本发明公开了一种混凝土制品表面裂纹化学防腐修补材料及制备方法与施工方法，修补材料，由以下重量份的组分组成：水泥400-500份，细沙600-700份，水130-160份，环氧树脂稀释液50-80份，乙二胺5-10份，酒精70-80份，环氧树脂稀释液与水的用量之和为205-215份；环氧树脂稀释液的质量分数为70-90％。本发明的修补材料可以对产生的裂纹进行良好修复，防止产生裂纹的混凝土制品继续腐蚀。采用本发明配置的修补原料具有很好的抗渗性，可防止水渗入裂纹对混凝土制品内部继续腐蚀，从而提高了混凝土制品的使用年限。
摘要（英）：

The invention discloses a concrete product surface crack chemical corrosion damage repair material and a preparation method and construction method thereof. The repair material comprises, by weight, 400 to 500 parts of cement, 600 to 700 parts of fine sand, 130 to 160 parts of water, 50 to 80 parts of an epoxy resin diluent, 5 to 10 parts of ethylenediamine and 70 to 80 parts of alcohol, wherein the sum of the epoxy resin diluent and water is 201-215 parts by weight and a mass fraction of the epoxy resin diluent is 70-90%. The repair material can well repair cracks, can prevent corrosion of the concrete product with cracks, has good impermeability, can prevent concrete product interior corrosion caused by water permeation into cracks and can improve a service life of the concrete product.
