摘要
通过初步试验确定原材料并优化配比后,自制了水泥基渗透结晶型防水剂IOC。将IOC防水剂和市场流通的防水剂LLH进行抗压强度实验、吸水率试验、碳化深度实验、抗氯离子渗透实验、抗化学侵蚀实验、自愈合性能试验等实验性能对比。结果表明:当IOC防水剂掺量为2%时,抗压强度比LLH防水剂实验组的提升了8.7%;平均电通量值降低了7.3%;其他性能除吸水率以外,均有不同程度的改善。自主研发的防水剂IOC具有良好的力学性能和防水性能,其实验数据明显优于市场流通的防水剂LLH。同时对自制的IOC防水剂进行性能验证和机理分析,对学界现有的防水机理进行归纳总结,并进行补充。
After determining the raw materials through preliminary tests and optimizing the ratio,the cement-based permeable crystalline waterproofing agent IOC was made.The IOC waterproofing agent and the market-circulating waterproofing agent LLH were tested for compressive strength test,water absorption test,carbonization depth test,chloride ion penetration test,chemical corrosion resistance test,self-healing performance test and other experimental performance comparisons.The results show that when the IOC waterproofing agent content is 2%,the compressive strength is 8.7%higher than that of the LLH waterproofing agent experimental group;the average electric flux value is reduced by 7.3%;other properties except water absorption have different degrees improvement.The self-developed waterproofing agent IOC has good mechanical properties and waterproof performance,and its experimental data is significantly better than the waterproofing agent LLH circulating in the market.At the same time,the performance verification and mechanism analysis of the self-made IOC waterproofing agent are carried out.Summarize and supplement the existing waterproof mechanism in the academic circle.
