Abstract

The invention provides a sandstone-shale-produced material special for a road, a slope protection and a canal as well as a manufacturing method of the material. Sandstones, coal slime and limestone raw materials are processed to be tiny fine powder, and then mixed uniformly according to a specified proportion; the fine powder is flattened in a firing mold and is once and integrally fired in a high-temperature firing furnace for cooling molding. The manufacturing method comprises the follow steps: preparing raw materials, distributing the materials, firing, and cold machining to obtain finished products. The material special for the road, the slope protection and the canal, which is produced by taking sandstone and coal slime as the raw materials, has the advantages that the environment pollution problem is solved, the production cost is reduced, the utilization rate of the resource is increased, the waste is changed into the wealth, and the environment is optimized; by taking the coal slime as the raw material, a combustion supporting effect of raw material self combustion in a firing procedure is realized, the firing speed can be increased, and the fuel cost and the energy consumption are reduced.

Description

Technical field: [0001] The invention relates to the technical field of engineering materials, in particular to a special material for roads, slope protection and water channels produced by using sandstone shale and a manufacturing method thereof. Background technique: [0002] Microcrystalline foam integrated material is a newly developed high-grade environmental protection decoration material in the market. It is a resource utilization of solid waste such as desert drift sand, coal gangue, fly ash, various tailings slag, construction waste and so on. Green and environmentally friendly materials produced by turning harm into profit and turning waste into wealth. It has the characteristics of fire prevention and heat preservation, low thermal conductivity, new light weight, stable chemical properties, non-toxic and tasteless, anti-corrosion and moisture-proof, sound insulation and noise reduction, excellent waterproof and hydrophobic properties, insect-proof and mildew-proof...
