Improved curing agent for reinforcing treatment of silty clay and preparation method thereof
The invention discloses an improved curing agent for reinforcing treatment of silty clay and a preparation method of the improved curing agent. The improved curing agent is prepared from a main curing agent, an additive and a hydrating agent in proportion. The preparation method of the silty clay improved solidified soil comprises the following steps: pretreating silty clay; sequentially adding the main curing agent and the additive, and stirring and mixing; adding a glue solution prepared from water, water glass and PAM, and stirring to form a cement-soil mixture; the cement-soil mixture is put into a mold to be compacted and formed; and maintaining to a specified age at a certain temperature and humidity to obtain the silty clay improved solidified soil. According to the method, the problem of reinforcing treatment of southern silty clay is solved, cohesion among soil particles is increased, a soil body is solidified, meanwhile, the microstructure of the soil body is improved, and the strength of the soil body is improved.
一种用于粉质黏土加固处理的改良固化剂及其制备方法，所述改良固化剂由主固化剂、外掺剂和水化剂配比而成。粉质黏土改良固化土的制备方法包括：粉质黏土进行预处理；依次加入主固化剂和外掺剂，搅拌混合；将由水、水玻璃和PAM制备的胶水溶液加入搅拌形成水泥土拌合物；将水泥土拌合物放入模具振实成型；在一定温度和湿度下，养护至规定龄期，得到粉质黏土改良固化土。所述方法解决了南方粉质黏土加固处理问题，增大了土颗粒之间的内聚力，土体实现了固化，同时也改善了土体的微观结构，增加了其强度。
