摘　　要：以城市建筑垃圾、炉底渣和石粉等区域特色的固体废弃物为再生骨料制备环保砖,系统考察了骨料对环保砖机械性能的影响。试验结果表明:再生骨料的种类对环保砖抗压强度的影响显著。随着再生骨料中混凝土块的增加,环保砖抗压强度逐渐增加;而随着再生骨料中黏土砖含量的增加,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。该方法有望解决在城市化进程中出现的大量建筑垃圾,实现建筑废弃物的循环再利用。By taking the solid wastes of the urban building garbage, dregs of hearth and stone powders as the recycledbone materials for the environmental protection brick preparation, the paper studies the effect of bone materials on the mechanicalproperties of the environmental protection brick. The result shows that the species of bone materials shows obvious influenceon compressive strength of the environmental protection brick. With the increasing of the concrete block in the recycled bonematerials, the compressive strength of the environmental protection brick will increase gradually. While the increasing of thecontent of clay brick in the recycled bone materials, the compressive strength of the environmental protection brick will reduceobviously; with the increasing of the content of dregs of hearth, the compressive strength of the environmental protection brickwill reduce; the stone powders see a upgrading role on the compressive strength of the environmental protection brick. Theprocess is expected to solve the problem of a great lot of building garbage arisen in the course of urbanization and to realizethe recycling and reuse of the building wastes.
