Inorganic soil curing agent and preparation method thereof

Abstract

The invention relates to an inorganic soil curing agent and a preparation method thereof, relating to soil curing agents for building and a preparation method thereof; the curing agent comprises 28-45% of cement clinker, 30-45% of two-grade or more than two-grade coal ash, 10-15% of slag, 12-15% of quicklime, 1-3% of ardealite and 2% of alkali activator; the preparation method comprises the following steps: transporting raw materials to a ball mill, grinding the raw materials for 12-15 minutes; stirring evenly so as to form gray powder material, wherein a specific surface area is 280-300m<2>/kg; sieve residue is not more than 4% through a square hole screen of 80 microns; mixing 6-15% of the soil curing agent with loosened soil in a construction procedure; and grinding under condition of a best moisture content of soil, and obtaining a product after a conservation period. According to the invention, the inorganic soil curing agent can be mixed with material prepared by mixing soil, garbage, and industrial waste through methods of regulating curing agent component proportion, dosage and the like, and is suitable for the inorganic soil curing agent of various soil textures.

Description

technical field [0001] The invention relates to a soil curing agent for construction and a preparation method thereof, in particular to an inorganic soil curing agent and a preparation method thereof. Background technique [0002] The traditional process used for road foundations is the use of cement to stabilize sand and gravel. With the development of the economy and the increasing traffic volume, road construction has entered a stage of rapid development. Road construction materials that meet the needs of the project are also in short supply. In recent years, gravel, an important natural resource required for road construction and construction, has been decreasing day by day, and some areas are close to exhaustion. Especially in the old road reconstruction project, the old soil of the original road is transported out, and the sand and gravel of the new road are transported to the site from a long distance from a long distance, which greatly increases the project cost. ...
