摘要
采用渗透型涂料、成膜型涂料和两种涂料复合三种表面处理方式,对混凝土试件进行处理,通过透气试验、碳化试验和毛细吸水试验比较其防护效果。结果表明:两种涂料复合使用能够有效地阻止CO2和水向混凝土内部扩散和迁移,效果最佳;只用成膜型涂料的效果次之;渗透型涂料也能显著地降低水进入,但几乎不能阻止CO2的进入。
Three coating methods, i.e., the permeable coating, the film forming coating and the combined both were used to treat the surface of specimens. Their protective effects on concrete were investigated via the carbonation and capillary water adsorption tests. The results show that the combined application has the optimum efficiency to prevent the diffusion and migration of CO2 and H2O into the concrete. The second is the film forming coating. The permeable coatings could reduce the water into the concrete, but hardly prevented CO2.
