孔填充材料对混凝土抗渗性能影响研究

Research on effect of hole filling material to the impermeability of concrete

随着混凝土在我国建筑工程中运用的越来越广泛,混凝土的耐久性问题逐渐显现出来,成为混凝土性能研究的重点,而混凝土的开裂渗漏是引起混凝土耐久性问题的重要原因。首先确定基准混凝土的配合比,然后通过试验研究孔填充修复材料对混凝土抗渗性能的影响,进一步探索了表面活性剂对孔填充材料抗渗透性能的提高作用,对加强混凝土抗渗性能,提高混凝土耐久性有重要作用。

With the concrete used more and more widely in building projects in China, the problem of durability was gradually revealed, became the focus of the concrete performance study, and the concrete cracking leakage was the main cause of the concrete durability problem.First, determined the mixing ratio of the benchmarks concrete, then did experimental study on effect of hole filled repair materials to concrete impermeability, then did further experiment to explore the effect of surfactant to increase the role of pore filling material.It did important role to reinforced the concrete impermeability and improve the durability of concrete.
