Abstract

The invention discloses a high-molecular soil curing agent, and belongs to the building material technology field. The high-molecular soil curing agent is prepared from the following components, by weight, 4-8 parts of ordinary portland cement, 35-45 parts of binding agent, 15-25 parts of reinforcing agent, 4-6 parts of early strength agent, 4-9 parts of waterproof agent, 7-9 parts of filling agent, 2-4 parts of water reducer, 0.3-0.7 part of surfactant, 4-6 parts of dispersant and 0.01-0.03 part of air entraining agent. The soil curing agent has advantages of reasonable formula, large penetration depth (18mm), large compressive strength (the 7-day unconfined compressive strength is 12.42MPa), and high water resistance (the 7-day immersion water absorption is 0.86%), and can be applied to engineering of roads, railways, subways and the like.

Description

technical field [0001] The invention relates to a polymer soil solidifying 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 ac...
