摘　　要：将废弃混凝土和铁尾矿砂加工成再生骨料,用于配制全再生混凝土空心砌块,这对回收利用废混凝土和铁尾矿砂具有重要的现实意义。提出了利用废混凝土及铁尾矿砂配制全再生骨料混凝土空心砌块配合比的设计步骤和计算方法,并以强度等级为MU7.5的全再生骨料混凝土空心砌块为例进行了实例设计计算。The waste concrete and iron ore tailings used as recycled aggregates in the production of the recycled concrete hollow blocks which is very important for reusing the waste concrete and iron ore tailings.It presents design procedure and calculation method of mix pro- portion of concrete hollow blocks with full recycled aggregates using the waste concrete and iron ore tailings.As an example of calcula- tion, the mix proportion design of regeneration concrete hollow block with strength grade MU7.5 was discussed.
