全固废免烧制砖的原料配比研究及应用

Research and application of raw material ratio for all solid waste non burning brick making

建筑垃圾作为我国城市单一品种排放量最大、最集中的固体废弃物,对其进行合理有效的处理,是城市可持续发展的重要一环。本文从原料配比出发,以建筑垃圾、钢渣及胶凝材料为主要原料,研究产品抗压强度以及外观指标与不同配比间的变化规律。通过实验结果确定出最优原料配比,并成功应用于工业生产。对实际运行项目进行环境及经济效益分析评价,与传统方式制作标砖,本文所讨论的全固废生态砖的原料成本降低约65.6%,生产过程的碳排放减少约93.3%。

Construction waste,as the largest and most concentrated solid waste in China's urban areas,requires reasonable and effective treatment,which is an important part of urban sustainable development.This article starts from the raw material ratio and uses construction waste,steel slag,and cementitious materials as the main raw materials to study the variation laws of product compressive strength and appearance indicators with different ratios.The optimal raw material ratio was determined through experimental results and successfully applied in industrial production.By analyzing and evaluating the environmental and economic benefits of actual operational projects,compared to traditional methods of producing standard bricks,the raw material cost of the solid waste ecological brick discussed in this article has been reduced by about 65.6%,and the carbon emissions during the production process have been reduced by about 93.3%.
