Abstract

The invention discloses a high osmosis type soil hardener, which is bicomponent seriflux containing materials of hardener and main liquid, and is characterized in that the volume ratio of hardener to main liquid is 1: (0.8-2). Since bicomponent seriflux disclosed by the invention is aqueous solution with low viscosity, the bicomponent seriflux can effectively seep into a small gap of 0.001mm, and good hardening of soil can be realized; the strength of sodium silicate in the components is large by hardening of acidity and ester materials, additionally, soil plays a role of enhancement, so that the strength of consolidation materials reaches around 10-15MPa; by the adoption of polyacrylic acid materials and polyacrylic ester materials as hardener for sodium silicate, the tenacity is good, additionally, certain amount of flexible materials such as polyacylamide are used for increasing the tenacity of sodium silicate hardener, certain tenacity of sodium silicate hardener is realized after hardening soil, the mechanical property of hardened soil can be increased; and the hardener disclosed by the invention is low in cost, non-toxic and environmental-friendly.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a high-permeability soil curing agent with good soil curing effect and its use method. technical background [0002] Soil stabilizer refers to materials that can improve and enhance the physical and mechanical properties of soil. At the beginning of the 20th century, some economically developed countries used soil solidification technology to improve the soil in the construction of roads, ports, airports and anti-seepage projects, and achieved good results. In the 1970s, the United States, Japan, Germany and other countries carried out in-depth development of soil improvement technology, and the technical level has made great progress. The materials for soil modification have changed from the original single lime, cement, fly ash and water glass. , Developed to a new material specially used to strengthen the soil - soil stabilizer. At present, it has been widely us...
