Abstract

The invention discloses a soil curing agent, which belongs to the technical field of building materials. The soil curing agent comprises the following raw materials: common silicate cement, solid sulphur ash, an excitant, an early strength agent, silica fume, quick lime, polyacrylamide, water, polyvinyl butyral, calcium lignosulphonate, 3-amino propyl trialkoxysilane and polyvinylpyrrolidone. Theabove soil curing agent is prepared through the steps of carrying out material modification, mixing, vacuum preparation and the like. The soil curing agent has a simple preparation technology. When the soil curing agent is adopted, the solidification time of a roadbed can be obviously shortened, the compressive strength of the roadbed is improved, time limit for construction are shortened, and thesoil curing agent can be applied to the soil solidification of different soil textures.

Description

【Technical field】 [0001] The invention belongs to the technical field of building materials, and in particular relates to a soil curing agent. 【Background technique】 [0002] At present, our country is undergoing large-scale engineering construction. In engineering construction, due to limited natural resources, 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 will also cause serious natural disasters. The environmental damage degrades the quality of the social living environment. In engineering construction, if the cheap and widely sourced soil can be fully and effectively used as engineering materials, it can effectively save the amount of sand and gravel, reduce engineering costs, and reduce damage to natural resources while ensuring engineering construction. ecological environment and improve the quality of social life. Soil stabilizer is an engineering material th...
