渗透型涂料对水工混凝土防护效果的影响分析OA

In this paper,the effects of silane permeable coatings and their dosage on the protective effect of hydraulic concrete were explored by testing the chloride ion absorption,penetration depth,water absorption and surface hydrophobicity.The test results show that increasing the amount of silane permeable coating can significantly improve the protective effect of hydraulic concrete,especially for low-strength concrete,and paste silane has higher effective permeability and lower volatile loss than liquid silane,which can effectively reduce the absorption of chloride ions.The concrete surface treated with waterproof coating has good hydrophobicity,and the research results can provide an important reference and guidance for the protection of hydraulic concrete.
