摘要
探讨了沙柳材水抽提物(冷水和热水抽提物)对水泥水化特性的影响,以及添加化学助剂(助凝剂)后水泥凝结时间的变化。结果表明:沙柳材水抽提物是水泥的较强阻凝剂,热水抽提物的阻凝作用比冷水抽提物的大;化学助剂(助凝剂)可使水泥凝结时间缩短,其中施加CaCl_2的效果最为显著;同时,沙柳材冷、热水抽提物添加一定量的助凝剂可以使水泥的凝结时间缩短。
This article discussed the Influence on cement hydrating characteristic of cold water, hot water and chemical medication, The result indicated that water extraction of components in Salix psammophila retarded cement solidifying, and hot water extraction of components were more strict than that of cold water; chemical medication could shorten the solidlifying time of cement and the effect of CaCI2 was the best. Water extraction of components in Salix psammophila added chemical medication could shorten the of solidifying time.
