摘要:
为提高水工钢筋混凝土结构抗渗性能。根据水工混凝土服役环境的特殊性,设计开展室内混凝土防护材料性能检测试验方法,对比分析水工建设中应用较为广泛的HS943环氧厚浆、施而固、优止水以及永凝液4种防护材料的混凝土抗渗性能。试验表明:(1)HS943环氧厚浆与施而固防护材料涂层防渗效果明显。环氧厚浆材料内部微观结构密实无孔隙,能够阻止水分的渗入,而施而固材料内部微观结构及涂层阻水性则相反;(2)优止水材料成分与施而固相似,但涂层防渗效果较施而固差;(3)永凝液能填充结构内部孔隙但不能阻止水从结构表面进行浸入,涂层抗渗效果一般。
Abstract:
In order to improve the impermeability of hydraulic reinforced concrete structures, according to the particularity of the service environment of hydraulic concrete, an experimental test method for the performance of indoor concrete protective materials was designed. The impermeability of concrete with HS943 high build epoxy, solidification, excellent water-stop and permanent condensate, which were widely used in hydraulic construction, was compared and analyzed. The test results showed that:(1)The anti-seepage effect of two protective materials coating as HS943 high build epoxy and solidification was obvious. The internal microstructure of high build epoxy material was compact and porous, which could prevent water infiltration, while the internal microstructure and the water resistance of the coating of solidification material were opposite.(2)The composition of the excellent water-stop material was similar to that of solidification, but the coating anti-seepage effect of the excellent water-stop was worse than that of the solidification.(3)Permanent condensate could fill the internal pore of the structure, but could not prevent water from immersing from the structure surface, so that the coating anti-seepage effect was general.
