Problems solved by technology

These technologies use natural sand, stone, cement and construction waste as raw materials. However, no suitable excitation technology is used to excite the powder, and the surface of the aggregate is not strengthened, resulting in poor mechanical properties and low waste rate of the prepared slope protection materials.

Abstract

The invention belongs to the building material field, and particularly relates to a slope protection material and a preparation method thereof. The slope protection material comprises a cementing material, aggregates, modified aggregates, and water; the cementing material is prepared from cement, municipal solid wastes with a particle size of 1-3 mm, an exciting agent, and industrial waste residues; the aggregates are prepared from municipal solid wastes with a particle size of 1-3 mm; the modified aggregates are prepared from municipal solid wastes with a particle size of 4-10 mm, a surface reinforcing agent and water. The preparation method of the invention can make efficient use of municipal solid wastes, reduce resource and energy consumption caused by building material production, and is simple in production and construction process; the prepared slope protection material is high in mechanical properties; land occupation and environment pollution caused by stacking of municipal solid wastes are reduced; and the social, economic and environment benefits are remarkable.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a slope protection material and a preparation method thereof. Background technique [0002] In the process of urbanization, the municipal solid waste generated by the demolition of old buildings, new building construction and road construction every year reaches hundreds of millions of tons, accounting for 30-40% of the total urban waste. Municipal solid waste contains a large amount of water, calcium silicate and calcium hydroxide, which makes the percolation water strongly alkaline. A large amount of sulfate ions contained in waste gypsum will be converted into hydrogen sulfide under anaerobic conditions. Waste cardboard and waste Under anaerobic conditions, wood can dissolve lignin and tannic acid and decompose to produce volatile organic acids. Waste metal materials can make the percolation water contain a large amount of heavy metal ions, thereby polluting the s...
