摘要:
本文研究了膨胀剂掺量、硅灰掺量、水胶比降低对水泥砂浆膨胀率的影响。结果表明：膨胀剂掺量的增加会使浆体膨胀率大幅提升；掺加硅灰后，浆体膨胀率有大幅度降低；水灰比降低对膨胀率的影响较明显，会导致浆体膨胀率下降。
The influence of the proportion of expanding agent and silica fume and the changing of water- binder ratio on expansion rate of the mortar were studied in this paper. The results indicated that the expansion rate of the mortar was enhanced with the increasing of the expansion agent, and reduced with the adding of the silica fume and the decreasing of the water-binder ratio.
