Study on Permeability of Concrete Coated with Silicone Waterproofing Agent under Load

对硅烷表面防水混凝土试件进行了弯曲试验,测定在不同应力作用下试件的抗水渗透性和抗氯离子渗透性。结果表明,试件的抗水渗透性、抗氯离子渗透性均随着作用应力的提高而降低,但是在不同应力作用下,硅烷表面防水试件较空白试件具有更好的抗渗透性。文章指出,对混凝土结构进行硅烷表面防水处理可以提高其耐久性并延长使用寿命。

Resistances to water and chloride ion penetration of concrete samples coated with silicone waterproofing agent under different bend stresses are tested. The results show that the resistances to water and chloride ion penetration of samples reduces with the increasing of bend stress, but samples coated with silicone waterproofing agent have better impermeability than blank samples under different stresses. The article points out that concrete structures coated with silicone waterproofing agent will have better durability and longer service life.
