摘要: 随着我国城市化和工业化进程的快速推进,城市建设产生大量的建筑废弃物,燃煤电厂产生大量炉底渣,建筑固废的处置在城市可持续发展过程中备受关注。以建筑垃圾再生骨料、炉底渣和石粉等区域特色的骨料制备环保砖,系统考察了骨料对环保砖力学性能的影响。实验结果表明,再生骨料的种类对环保砖抗压强度的影响显著。再生骨料中混凝土的增加,环保砖抗压强度逐渐增加;而再生骨料中粘土砖含量的增加,环保砖抗压强度明显降低。环保砖抗压强度随炉底渣的含量增加而降低,石粉对环保砖抗压强度有提升作用。

Abstract: In the process of China urbanization and industrialization, construction wastes are generated at an increasing rate and a huge amount of furnace bottom ash are generated in coal-fired power plants. Much attention is paid to the disposal these solid wastes in the process of sustainable development. In this study, the effect of aggregates, including recycled construction waste aggregate, furnace bottom ash, and stone powder, on the mechanical properties of environment-friendly block (en-block) was investigated systematically. The results indicated that the types of recycled aggregates had significant effect on the compressive strength of en-block. The compressive strength increased with the increasing content of the recycled concrete, and deceased evidently with the increasing content of brick. The compressive strength of en-block decreased with the increasing content of furnace bottom ash, and can be enhanced by stone powder.
