硅烷耦合剂改良混凝土在防水工程中的应用研究

Application Research of Improved Concrete with Silane Coupling Agent in Waterproofing Works

通过对不同硅烷耦合剂掺量的防渗混凝土进行吸水性、氯离子电通量及微观电镜扫描试验,研究了硅烷耦合剂对混凝土防渗性的影响。研究结果表明,硅烷耦合剂可有效增强改良混凝土的防水性能与抗氯离子渗透性能,且当硅烷耦合剂掺量为2%时,混凝土的抗渗性能最好。该研究成果可为地铁防水工程建设提供良好的借鉴和参考。

The effect of silane coupling agent on concrete permeability resistance are studied by experiments of water absorption,chloride ion electric flux and micro scanning electron microscope of impervious concrete with different amount of silane coupling agent.The results show that the silane coupling agent can effectively improve the water-proof performance and chloride ion penetration resistance.When the content of silane coupling agent is 2%,the concrete permeability resistance is the best.The research provide good references for the waterproof engineering con-struction in subway.
