In recent years there has been an increasing tendency to recycle the wastes generated by building companies in the construction industry, demolition wastes being the most important in terms of volume. The aim of this work is to study the possibility of using recycled aggregates from construction and demolition wastes in the preparation of precast non-structural concretes. To that purpose, two different percentages (15% and 30%) of natural aggregates were substituted by recycled aggregates in the manufacture of paving blocks and hollow tiles. Dosages used by the company have not been changed by the introduction of recycled aggregate. Precast elements have been tested by means of compressive and flexural strength, water absorption, density, abrasion, and slipping resistance. The results obtained show the possibility of using these wastes at an industrial scale, satisfying the requirements of the Spanish standards for these elements.
近年来，建筑行业中建筑公司产生的废弃物回收利用的趋势日益增强，就体积而言，拆除废弃物是最重要的。这项工作的目的是研究在预制非结构混凝土制备中使用建筑和拆除废弃物再生骨料的可能性。为此，在制造铺路砖和空心砖时，用再生骨料替代了两种不同比例（15%和30%）的天然骨料。公司使用的剂量并未因引入再生骨料而改变。预制构件已通过抗压强度、抗弯强度、吸水率、密度、耐磨性和防滑性进行了测试。所得结果表明，在工业规模上使用这些废弃物是可能的，满足了西班牙这些构件标准的要求。
