Analyses of the Protective Effect of Polyethylene-Triethoxysilane and Triethoxysilane Emulsion Coatings on Concrete Substrate

Abstract:

Water could transport aggressive substances such as carbon-dioxide, sulfates and chloride ions in reinforced concrete structures. By penetration, the stability of the whole structure is influenced. This paper deals about waterproof effect and chloride resistance of two kinds of silane coatings, polyethylene-triethoxysilane and triethoxysilane emulsions on concrete substrate along with the mechanism of the hydrophobic action. The results, in terms of visual observations, chloride test and water absorption test, showed that the two silane coatings could reduce the chloride penetration and the water absorption efficiently. The comparison between the two indicates that polyethylene-triethoxysilane penetrates little when applied on the substrate, but it performs better waterproof effect and is more efficient to chloride penetration.
