Waste residue concrete brick and preparation method thereof
The invention provides a waste residue concrete brick and a preparation method thereof, and relates to the technical field of concrete bricks. The waste residue concrete brick provided by the invention is prepared from the following raw materials in percentage by weight: 10%-30% of carbide slag, 7%-20% of fly ash, 20%-40% of phosphogypsum, 5%-15% of a modifier, 1%-5% of a water reducing agent and 15%-35% of aggregate filler, the autoclaved brick is prepared through stirring and mixing, primary powder mixing, digestion and aging, secondary powder mixing, compression molding and autoclaved curing, the finished autoclaved brick is smooth in appearance, the flexural and compressive strength meets the use requirements, and the qualified rate of the finished product is high; the utilization rate of solid waste can be effectively increased, the harm to the environment is reduced, the comprehensive utilization concept of waste in the national medium-and-long-term scientific and technological development planning outline is met, the national requirement for environmental protection is met, and energy conservation, emission reduction and waste recycling are achieved.
本发明提供一种废渣混凝土砖及其制备方法，涉及混凝土砖技术领域。本发明提供的废渣混凝土砖包括以下重量百分比的原料：电石渣10％～30％、粉煤灰7％～20％、磷石膏20％～40％、改性剂5％～15％、减水剂1％～5％、以及15％～35％骨料填充；经搅拌混合、一次粉混、消解陈化、二次粉混、压制成型、蒸压养护制成蒸压砖，成品蒸压砖外观平整，抗折抗压强度满足使用要求，成品合格率较高；能够有效提高固体废弃物的利用率，降低对环境的危害，符合国家中长期科技发展规划纲要中对废弃物的综合利用理念，并符合国家对环境保护的要求，实现了节能、减排以及废物再利用。
