Abstract

The invention provides a soda saline-alkaline soil anti-freeze cracking curing agent, which belongs to the technical field of soil curing agents. It solves the problem of insufficient strength and frost crack resistance of the existing solidified soda saline-alkali soil. The curing agent is composed of cement, anhydrous sodium silicate, water reducing agent and short basalt fiber. Using the curing agent of the present invention, the strength can reach 12MPa-15MPa; the impermeability permeability coefficient reaches (10 ‑6 -10 ‑7 ) cm / s, the number of freeze-thaw cycles reached F80‑F100, and the freeze-crack resistance performance has been greatly improved. Simultaneously, the raw materials of the curing agent of the present invention are all harmless to the environment, and are eco-friendly.

Description

technical field [0001] The invention belongs to the technical field of soil solidifying agents, and in particular relates to a soda saline-alkaline soil anti-freeze cracking solidifying agent. Background technique [0002] Soda saline-alkali soil is widely distributed in the western part of Jilin, my country. It is one of the three largest soda saline-alkali soil distribution areas in the world and the largest soda saline-alkali soil distribution area in my country. It is prone to dissolution and subsidence, and the phenomenon of water and soil loss is serious. At present, the traditional saline-alkali soil curing technology is mostly used on roadbeds. After the curing agent is cured, the strength of the soil is high, but the high cost is not conducive to popularization; the current research on the ionic curing agent is less, and the curing effect is not obvious. Contents of the invention [0003] The invention provides a soda saline-alkaline soil anti-freeze-cracking typ...
