摘要
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。
The paper mainly studied the properties of CSA expansive agent. The results show that the expansive rate can reach 0 25‰ in 7 days when percentage addition of CSA reach 8%, it means that expansive property of CSA\|Ⅱ is much more better than that of others. We also made the test of expansion and shrinkage of it, and found that restrained expansion rate of concrete increased clearly, so did the compressive strength etc.. The paper analyzed the expansion mechanism of expansive agent also. \[
