暴露在腐蚀性水环境下的混凝土结构的破坏是各种工业、桥梁设施面临的主要问题。在混凝土结构表面涂刷保护涂料是一种避免混凝土遭受破坏的简单可行的办法。本文介绍了涂覆乙烯基苯丙烯酸硅烷涂料的圆柱体和立方体砂浆试块在3%硫酸溶液、7000mg/l的无水硫酸钠溶液和模拟海水环境中侵蚀试验,结果显示经过这种硅烷涂料处理的砂浆试块具有优异的耐海水和抵抗硫酸盐的能力,但是在3%硫酸溶液中,试块的表面被严重破坏,重量变化明显。 The destruction of concrete structures exposed to corrosive water is a major problem faced by various industrial and bridge facilities. Applying a protective coating on the surface of a concrete structure is a simple and viable solution to prevent concrete damage. In this paper, the corrosion tests of cylinder and cube mortar coated with vinylbenzene acrylic silane coating in 3% sulfuric acid solution, 7000 mg / l anhydrous sodium sulfate solution and simulated seawater environment were carried out. The results show that after this silane coating treatment Mortar block has excellent resistance to seawater and sulphate resistance, but the surface of the test block is severely damaged in 3% sulfuric acid solution and the weight change is obvious.
