Powdery soil improving agent and applications of powdery soil improving agent in improvement of powdery soil

The invention discloses a powdery soil improving agent and applications of the powdery soil improving agent in improvement of powdery soil. In the prior art, powdery soil has disadvantages of insufficient viscosity and insufficient water retention, is usually directly discarded after excavation, and is difficultly used in engineering construction, such that the engineering cycle is prolonged, thecost is increased, and the powdery soil is difficultly treated. A purpose of the present invention is to solve the problems in the prior art. The powdery soil improving agent comprises, by mass, 15-25parts of cement, 3-6 parts of quicklime, 2-6 parts of sodium carboxymethylcellulose, and the like. According to the present invention, with the application of the powdery soil improving agent in engineering practice, by using the powdery soil as the action object, through the effect of the improving agent, the prepared improved body has good strength, the long-distance transportation of the powdery soil is effectively avo
