摘要
系统研究了不同品种的硅烷浸渍剂对高性能混凝土的防水防腐保护的影响,探讨了冻融循环、酸碱环境、涂覆量等因素对混凝土防腐保护性能的影响。试验结果表明,硅烷浸渍剂对高性能混凝土有着非常好的防护效果,吸水率显著下降,氯化物吸收量降低值大于93%,渗透深度达到3mm以上,具有良好的抗冻融循环和耐酸碱性。最佳用量为300mL/m2。
Effects of different silcane in protecting high performance concrete from corrosion are studied.The effects of freezing-melting circulation, acid and base environment, usage are discussed.The results showed that silcane impregnant has perfect properties in protecting high performance concrete from corrosion, which make water absorption decrease obviously, the absorption value of chloride ion reduced by more than 93%, and penetration depth was over 3 mm.It has good anti-melting circulation and acid ＆ alkaline resistant.Optimum usage was 300 mL/m^2.
