一种混凝土结构用硅质防护剂的性能测试与分析

Performance Test and Analysis of a Silicious Protector for Concrete Structure

混凝土的抗渗性能对混凝土受外界不利因素的侵蚀程度有着极其重要的影响。通过在混凝土表面喷涂或涂刷防护剂可以有效提升混凝土的抗渗性能。文中对一种混凝土结构用硅质防护剂进行吸水率比、抗碱性、渗透深度三项性能进行测试,研究其在不同涂刷次数下对混凝土结构抗渗性能的影响。研究结果表明:当涂刷次数为8次以上时,混凝土结构具有良好的抗渗性能。

The impermeability of concrete has an extremely important influence on the erosion degree of concrete by external adverse factors.The impermeability of concrete can be effectively improved by spraying or brushing protector on the surface of concrete. Water absorption ratio,alkali resistance and penetration depthof a silicious protector for concrete structure are testedand the impermeability of the concrete structure under different brushing times is studied in this paper. The results show that the impermeability of concrete structure can be improved effectively when the brushing times reach 8 times.
