摘要
建筑垃圾通过回收加工而得到的再生骨料,可作为生产再生骨料混凝土砌块的原材料,建筑垃圾再生骨料的组成与用量对混凝土砌块的性能有显著的影响。建筑垃圾中废烧结砖再生骨料用量的变化将引起混凝土砌块强度的变化,随着废烧结砖再生骨料用量的增加,混凝土砌块的吸水率增加,表观密度、抗压强度、软化系数等性能会有所下降。
Construction waste can be recycled as raw material to produce aggregate concrete block, the composition and amount of construction waste recycled aggregate has a significant impact on the performance of concrete block. Waste fired brick construction waste recycled aggregate amount will change the strength of concrete block. With the increase of the aggregate amount and the water absorption of concrete block, apparent density, compressive strength, softening coefficient of performance will decline.
