| 摘 要： | 系统地研究了铝酸盐和三乙醇胺含量对液体速凝剂性能的影响,结果表明：铝酸盐和三乙醇胺含量对液体速凝-剂的性能有很大影响,随着铝酸盐含量的增加,水泥的初凝、终凝时间都缩短,1d抗压强度先增大,后降低,而28d抗压强度比则逐渐降低;随着三乙醇胺含量的增大,水泥的初凝、终凝时间变化不明显,1d抗压强度总体上呈增大趋势,而28d抗压强度比则逐渐降低.

| Abstract: | the effectof aluminate and lriethanolamine on the properties of liquid flash-setting agent, and the results indicate that the effect of aluminate and uiethanolamine on the properties of liquid flash-setting agent is dramatic, with the increase of content of aluminate, the initial and finial setting time of cement decrease, compression strength after one day increases first and then falls, but compression strength with after 28 days decrease continuously. With the increase of content of triethanolamine, the initial and finial setting time change indistinctively, but compression strength after one day increases as a whole, compression strength with after 28 days decrease continuously. |
