Cement-based pressed wall material mainly prepared from waste brick slag and preparation method of cement-based pressed wall material
The invention discloses a cement-based pressed wall material mainly prepared from waste brick slag and a preparation method thereof, the raw materials of the wall material comprise waste brick slag, coarse sand, cement and water, the mass ratio of the waste brick slag to the coarse sand to the cement is 38-44.6: 38-44.6: 10.8-24, the particle size of the waste brick slag is 6-15mm, the water content of the wall material is 3-6%, and the particle size of the coarse sand to the cement is 6-15mm. The preparation method comprises the following steps: (1) mixing and stirring the waste brick slag, the coarse sand and the cement; (2) adding water and continuously stirring; (3) compacting and molding; and (4) curing and forming according to a cement-based product. The high-proportion waste brick slag is doped into the wall material, while the solid waste utilization rate is greatly increased, coarse aggregate is replaced with the waste brick slag, building sand with good grading is still adopted as other aggregate, the standard of the building sand is met, in addition, a ramming forming process is adopted, the water-binder ratio and the cement amount are reduced under the same strength, and the cost is reduced. The prepared wall material has excellent thermal insulation performance and compressive strength.
本发明公开了一种废砖渣为主的水泥基压制墙体材料及其制备方法，墙体材料的原料包括废砖渣、粗砂、水泥和水，废砖渣、粗砂、水泥的质量比为38‑44.6:38‑44.6:10.8‑24，废砖渣的粒径为6‑15mm，墙体材料的含水量为3‑6％，制备方法按以下步骤：(1)将废砖渣、粗砂与水泥混合搅拌；(2)加水继续搅拌；(3)夯压成型；(4)按水泥基制品养护成型。本发明在墙体材料中掺入高占比的废砖渣，在大幅提高固废利用率的同时，利用废砖渣代替粗骨料，其他骨料仍采用级配良好的建筑用砂，满足建筑用砂标准，此外，本发明还采用了夯压成型工艺，实现了同等强度下，减少了水胶比和水泥量，制得的墙体材料具有优异的保温性能和抗压强度。
