摘要
研究了粘土固化浆液结石体无侧限抗压强度ｑｕ的增长规律及其影响因素，得出以下结论：粘土固化浆液无侧限抗压强度随时间的增加而增长，其初期强度增长较快，后期强度增长较慢；增加水泥的加量将提高浆液的ｑｕ值，固化剂Ａ的加量有一最佳值（３％左右）；因固化剂Ｂ是作为加快水泥水化反应速度的催化剂而加入的，所以，固化剂Ｂ的加量以控制在５％以下为好。此外，还简单分析了粘土固化浆液结石体无侧限抗压强度与塑性强度存在差异的原因。
The strength of grouts is a very important performance parameter during grouting. The affecting factors and growing rule of unconfined compressive strength of clay hardening Grouts (CHG) were studied. The results showed that the unconfined compressive strength of CHG increases with the increasing of time; the early strength increases quickly, and the late strength increases slowly; increasing cement amount will increase the strength of CHG; the best amount of solidified agent (SA) A is 3%, the amount of SA B should be controlled under 5% because SA B is added into CHG as a catalyst increasing action rate of cement hydration. And then the reason that causes the difference between unconfined compressive strength and plastic strength of CHG was simply analyzed.
