Application of cement-based cementing slurry to preparation of solidified soil
The invention belongs to the technical field of building material engineering, and particularly relates to application of cement-based cementing slurry to preparation of solidified soil. The method comprises the following specific steps: uniformly mixing and stirring the cement-based cementing slurry, the soft soil, the water, the soil dispersing agent and the shrinkage compensating agent in proportion; after pouring forming, film covering curing is conducted, then normal-temperature curing is conducted, and finally the cement-based cementing slurry solidified soil is formed. On the basis of fully utilizing concrete centrifugal slurry, through modification and a special process method, the construction slump of the prepared solidified soil is 80-200 mm, the strength after hardening is 0.5-10 MPa, the shrinkage rate is smaller than or equal to 0.11%, and the comprehensive performance is good.
本发明属于建筑材料工程技术领域，具体涉及一种水泥基胶结料浆制备固化土的用途。具体步骤为：按比例将水泥基胶结料浆、软土、水、土壤分散剂和收缩补偿剂，混合搅拌均匀；浇筑成型后覆膜养护，然后常温养护，最终形成水泥基胶结料浆固化土。本发明在充分利用混凝土离心料浆的基础上，通过改性和特殊工艺方法，制备的固化土施工坍落度为80～200mm，硬化后强度为0.5MPa‑10MPa，收缩率≤0.11％，综合性能良好。
