Solid waste-based wet spraying concrete as well as preparation method and application thereof
The invention discloses solid waste-based wet spraying concrete as well as a preparation method and application thereof, and belongs to the field of building materials. The solid waste-based wet spraying concrete comprises the following components: 15%-20% of a cementing material, 60%-80% of aggregate, 0.2%-0.5% of a water reducing agent and the balance of water. Based on 100% of the mass of the cementing material, the cementing material comprises 30%-60% of water-quenched blast furnace slag, 20%-50% of steel slag and 10%-20% of desulfurized gypsum; based on 100% of the mass of the aggregate, the aggregate comprises 60% of copper smelting slag and 40% of barren rock. The method comprises the following steps: S1, mixing a cementing material and water according to a mass ratio of 10: (6-7) to obtain a slurry mixture; and S2, uniformly mixing and stirring aggregate, a water reducing agent and the slurry, filling into a mold, and carrying out vibration molding, so as to obtain the solid-waste-based wet-spraying concrete. The composite material can be applied to roadway engineering support and building application materials of mines.
本发明公开了一种固废基湿喷混凝土及其制备方法和应用，属于建筑材料领域。所述固废基湿喷混凝土包含以下组分：15％～20％的胶凝材料、60％～80％的骨料和0.2％～0.5％的减水剂，其余量为水。以所述胶凝材料的质量为100％计，胶凝材料包括30％～60％的水淬高炉渣、20％～50％的钢渣和10％～20％的脱硫石膏；以所述骨料的质量为100％计，骨料包括60％的铜冶炼渣和40％的废石。所述方法包括：S1、胶凝材料与水以10:(6～7)的质量比混合，得到浆体混合物；S2、将骨料、减水剂与浆体混合搅拌均匀后装模，振动成型，得到固废基湿喷混凝土。本发明可应用于矿山的井巷工程支护和建筑应用材料。
