摘要
为了有效解决工程结构的腐蚀问题、提高工程结构的可靠性,增强结构的耐久性,采用复配单体防水材料,通过不同的水灰比、内掺量、喷涂次数为影响因素研究混凝土结构的防腐蚀性能,从两方面进行试验,研究复配单体防水材料对混凝土抗渗强度、吸水率的影响。结果表明:混凝土采用复配单体材料后,降低了混凝土的吸水率,降低幅度约为85%;有效地改善了混凝土的防腐蚀性能,提高了混凝土的耐久性,解决了防水材料同时作用互相排斥的问题,混凝土试件第二次抗渗强度与第一次相比的降低了8%～16%,提高了二次抗渗强度。对混凝土结构的可靠性和耐久性具有重要价值。
In order to effectively solve the problem of corrosion engineering structure to improve the reliability of engineering structures,enhance the durability of the structure,the waterproof material compound monomer,through different water cement ratio,mixing amount,spraying times influence corrosion factors of concrete structure,experiments were carried out from two aspects,the research was single water proof material infiltration influence strength and water absorption resistance of concrete.The results show that the concrete with compound monomer material,reduces the concrete water absorption rate,decreased by about 85%.Effectively improve the corrosion resistance of concrete,improve the durability of concrete,waterproof material to solve the mutual exclusion effect at the same time,the concrete specimens second times compared with the anti permeability strength the first time decreased 8%～16%,improve the anti permeability strength of two.It is of great value to the reliability and durability of concrete structures.
