High-strength anti-freezing sludge solidified light soil and preparation method thereof
The invention discloses high-strength anti-freezing sludge solidified light soil and a preparation method, and the light soil is prepared from the following components in parts by weight: 160-200 parts of sludge slurry, 50-70 parts of a curing agent, 3-5 parts of foam, 1-2 parts of an anti-freezing agent and 0.2-0.4 part of a water reducing agent. The sludge solidified light soil has the advantages of light weight, high strength, good anti-freezing performance, good flowing property and the like, can greatly reduce filling and wall surface loads, reduce additional stress of a soft foundation, restrain settlement and lateral displacement of the soft foundation and simplify structural design of underground structures in an embankment, is good in early strength performance in winter, has outstanding advantages in construction in winter, and is suitable for large-scale popularization and application. The method can be applied to embankments, wharfs, roads and other scenes.
本发明公开了一种高强度防冻型淤泥固化轻质土及制备方法，所述轻质土按照重量份数，由下述组分组成：淤泥泥浆160‑200份、固化剂50‑70份、泡沫3‑5份、防冻剂1‑2份、减水剂0.2‑0.4份。本发明淤泥固化轻质土具有轻质、强度高、防冻性能好、流动性能好等优点，可大幅度地降低填土、墙面荷载，减少软基的附加应力，抑制软基的沉降和侧移，简化路堤中地下结构物的结构设计，并且冬季早强性能良好，对于冬季施工优势突出，可应用于路堤、码头、道路等场景。
