摘要
以膨胀剂(M-1)、乙基纤维素(EC)、明胶等为原料,采用溶剂蒸发法,制备了缓释膨胀剂LQ-1,并对其进行了性能评价。结果表明,缓释膨胀剂LQ-1可有效减小膨胀应力的释放,提高水泥石第一界面胶结强度100%以上,提高抗压强度20%,并具有一定的长期释放效果。
Controlled-release expanding agent LQ-1 was prepared with expanding agent( M-1),ethyl cellulose( EC) and gelatin as the materials with solvent evaporation method,and its performance was evaluated. The results have shown that controlled-release expanding agent LQ-1 is very effective in reducing the release of swelling stress,the cementing strength at the first interface of cement paste can be increased by more than 100% and the compression strength can be increased by 20% when it is used,and the swelling stress can be release in a prolonged period.
