搅拌法加固海相软土水泥外掺剂的选择

Selection of cement additive in treating marine soft soil with DCM

摘要: 针对深层搅拌法加固高矿化度海相软土强度形成的特点和目前水泥土外掺剂应用现状 ,提出了两点外掺剂选择的依据。并以此为理论指导 ,试验并优选出硅粉、粉煤灰、水玻璃等外掺剂 ,同时提供了部分试验数据。

Abstract: In this paper,according to the strength factors of marine soft soil treated with DCM and the practical application of the cement additive,two selective opinions were given.Meanwhile,the cement additive experiment has been carried out,and silica fume,flying ash,water glass were selected based on these opinions.Later some experimental data was offered.
