Abstract

The invention discloses a novel soil stabilizer, and belongs to the technical field of building materials. The soil stabilizer is prepared from following components by weight: 4-6 parts of common silicate cement, 25-35 parts of an adhesive, 15-25 parts of a fortifier, 4-8 parts of an early strength agent, 3-6 parts of a waterproof agent, 6-8 parts of a filler, 1-3 parts of a water reducer, 3-7 parts of a dispersant and 0.01-0.03 part of an air entraining agent. The soil stabilizer is characterized by a reasonable formula, a large depth of penetration (17 mm), high compressive strength (with unconfined compressive strength after 7 days being 12.23 MPa) and good waterproof performance (with the water absorption rate after water soaking for 7 days being 0.85%), and can be used for highways, railways, subways, and other projects.

Description

technical field [0001] The invention relates to a novel soil curing agent, which belongs to the technical field of building materials. Background technique [0002] Soil stabilizer is a composite material synthesized from various inorganic and organic materials to improve and enhance the technical performance of soil engineering. It has the advantages of fast curing speed, high early strength, long consolidation time, high late strength, less dosage, local materials, saving construction time and reducing project cost. has broad application prospects. [0003] There are many kinds of existing soil curing agents, but according to the development process of curing agents, they can be divided into lime cement curing agents, slag silicate curing agents, polymer curing agents and ion solution curing agents. Among them, the high polymer curing agent also includes various resins, fibers, surfactants and other curing agents. High polymer curing agent is a kind of surface active ag...
