本文主要研究了CSA膨胀剂的膨胀性能。通过研究发现Ⅱ型膨胀剂掺量为 8%时 ,7天膨胀率即可达 0 2 5‰ ,膨胀性能优于其他品种膨胀剂 ;同时我们进行了混凝土的胀缩实验 ,通过实验得出混凝土限制膨胀率明显增加 ,抗压强度、抗折强度也明显提高 ,混凝土抗渗性能明显改善。文章同时分析了CSA膨胀剂的膨胀机理
This article mainly studies the expansion properties of CSA expansion agent. Through the study, it was found that when the type II expansion agent content was 8%, the 7-day expansion rate could reach 0 2 5‰, and the expansion performance was better than that of other types of expansion agents. At the same time, we conducted concrete expansion and shrinkage experiments and obtained concrete through experiments. Limiting the expansion rate is obviously increased, the compressive strength and the flexural strength are also obviously improved, and the impermeability of the concrete is obviously improved. The article also analyzed the expansion mechanism of CSA expansion agent
