Problems solved by technology

This kind of soil solidification technology has the following disadvantages in the actual implementation: 1) the mechanical strength is limited, and it is often difficult to achieve the mechanical strength required for road construction due to the difference in soil quality; Mechanical strength, once the cemented structure is damaged by external force, it cannot be recovered, resulting in unsustainable overall mechanical strength

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 specifically relates to a soil rock gelling agent and a preparation method thereof. Background technique [0002] With the continuous development of society and economy, various basic projects have been constructed more and more, and the scale is getting bigger and bigger. In the traditional engineering construction process, a large amount of building materials such as cement, lime, sand and stone are needed. Because the mining and preparation of these building materials requires a large amount of natural resources and energy, and the construction often requires long-distance transportation of a large number of building materials. , So the energy consumption is high, the cost is high, and the environmental pollution is serious. [0003] Soil solidification technology came into being based on the above-mentioned status quo. It has been developing vigorously since the 1940s and has formed ...
