Abstract

The invention provides a soil curing agent which is prepared by the following steps: by taking industrial wastes as a main raw material, adding an excitant and a surfactant; uniformly mixing and grinding to powder with the Brinell specific surface area which is 300<m2> / kg-1000<m2> / kg; and then, stirring the powder at a middle speed for 30-40s, wherein the stirring speed is 300-400r / min. The industrial wastes consist of slag powder, coal ash, blast furnace slag powder and silica fume powder. The excitant consists of sodium sulfate, sodium chloride, magnesium chloride and magnesium chloride. The surfactant is sodium dodecyl benzene sulfonate. The soil curing agent provided by the invention is not only low in preparation cost and overcomes pollution to the environment by a lot of industrial wastes, but also facilitates to enhance the compactness of soil and improve the compressive strength and hydrolytic resistance of soil. In addition, the soil curing agent is simple in preparation process and simple and convenient to use, and the construction speed can be effectively improved, so that the soil curing agent can be widely applied.

Description

【Technical field】 [0001] The invention belongs to the technical field of engineering materials, in particular to a soil curing agent. 【Background technique】 [0002] At present, our country is undergoing large-scale engineering construction, and the amount of engineering has reached the peak in history. Due to the limited natural resources in engineering construction, the existing sand and gravel materials are far from meeting the growing needs of engineering construction. At the same time, the mining of sand and gravel has also caused serious damage to the natural environment, and the quality of the social living environment has declined. In engineering construction, if the soil with low price and wide sources can be fully and effectively used as engineering materials, it can effectively save the amount of sand and gravel while ensuring engineering construction, reduce engineering costs, reduce the destruction of natural resources, protect the ecological environment, and im...
