Abstract

The invention relates to a soilstone flocculant. The soilstone flocculant comprises the following components in percentage by mass: 5-15% of attapulgite, 5-12% of sepiolite, 3-48% of flyash, 5-37% of red mud, 2-30% of metallurgy iron-ore slags, 3-12% of bauxite, 0-17% of coal gangue, 0-8% of kaoline, 0-5% of sodium silicate, 1-3% of sodium hydroxide, 0-4% of monopotassium phosphate and 0.5-5% of urea. The soilstone flocculant has the beneficial effects that formula components are processed through a special preparation method, then soilstone flocculants with different proportions are designed according to different soil types and specific physicochemical property of soil, a geochemical engineering principle is applied to engineering application, and the inherent chemical property of soil is changed, so that the improvement of the physical structure and great improvement of the mechanical property of the soil are promoted, and the effects of high engineering mechanical strength and good stability are achieved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a soil rock coagulant and a preparation method thereof. Background technique [0002] With the continuous development of social economy, there are more and more various basic engineering constructions, and the scale is getting bigger and bigger. In the process of traditional engineering construction, a large amount of building materials such as cement, lime, sand and stone are needed. Because the mining and preparation of these building materials consume a lot of natural resources and energy, and in the construction, it is often necessary to transport a large amount of building materials over long distances. , so the energy consumption is large, the cost is high, and the environmental pollution is serious. [0003] Based on the above-mentioned status quo, soil stabilization technology emerged as the times require, and has flourished since the 1940s, and ha...
