文章用自制的不同种类再生骨料制备混凝土空心砌块。通过测试不同种类再生骨料、不同再生骨料掺量条件下的空心砌块抗压强度,分析再生骨料与混凝土空心砌块抗压强度的关系。结果表明,再生骨料会降低空心砌块抗压强度,再生骨料表观密度、吸水率等性能指标与空心砌块抗压强度呈良好的线性相关关系,再生砖骨料会显著降低混凝土空心砌块抗压强度。 The article uses self-made different kinds of recycled aggregate to prepare concrete hollow block. The relationship between recycled aggregates and compressive strength of hollow concrete blocks was analyzed by testing the compressive strength of hollow block with different types of recycled aggregates and different recycled aggregate contents. The results show that the recycled aggregate will reduce the compressive strength of hollow block, the apparent density of recycled aggregate, water absorption and other performance indicators showed a good linear relationship with the compressive strength of hollow block, recycled brick aggregates will significantly reduce the hollow concrete Block compressive strength.
