Problems solved by technology

[0002] At present, the research on soil stabilization and solidification technology in my country is still in a relatively backward state. The soil stabilization and stabilization materials are still dominated by cement, lime, fly ash or simple mixtures of these materials. Many problems have been solved, and it is difficult to meet the requirements of actual engineering, mainly reflected in poor early strength, large shrinkage, easy cracking, poor stability (water stability, freezing stability, thermal stability), etc., especially silty , sandy areas, these problems will be more prominent

Abstract

The soil curing agent as one kind of engineering material for curing and stabilizing various kinds of soil is especially suitable for curing silt and other kinds of low viscosity soil. The soil curing agent has main cement material comprising ore powder, flyash and water, as well as proper amount of alkali exciting component, expanding component and surfactant, and is prepared through mixing the materials and grinding to Blaine fineness of 3000-5000 sq m / kg. Specifically, it consists of mineral admixture 40-60 wt%, cement 15-25 wt%, alkali exciting component 5-15 wt%, expanding component 15-25 wt% and surfactant 0.01-0.1 wt%.

Description

technical field [0001] The invention relates to an engineering material capable of solidifying and stabilizing various types of soil, and is especially suitable for curing treatment of low-cohesive soil foundations such as silt, and belongs to the technical field of civil construction material manufacturing. Background technique [0002] At present, the research on soil stabilization and solidification technology in my country is still in a relatively backward state. The soil stabilization and stabilization materials are still dominated by cement, lime, fly ash or simple mixtures of these materials. Many problems have been solved, and it is difficult to meet the requirements of actual engineering, mainly reflected in poor early strength, large shrinkage, easy cracking, poor stability (water stability, freezing stability, thermal stability), etc., especially silty , Sandy areas, these problems will be more prominent. Contents of the invention [0003] Technical problem: the ...
