摘要
越来越多地拆除建筑物会产生大量的废弃混凝土块 ,既带来环境污染 ,又造成资源浪费。利用废弃混凝土块生产再生骨料代替天然砂石骨料配制再生混凝土的技术 ,采用再生粗骨料和天然砂组合 ,或再生粗骨料和部分再生细骨料、部分天然砂组合 ,制成的再生混凝土强度较高 ,具有明显的环境效益和经济效益。
Great quantity of concrete debris generated from more and more building demolition, which not only pollutes environment but also waste natural resources. To replace natural aggregate by waste concrete debris and then make recycled concrete is a technology of remarkable environmental and economical benefit. It proves the concrete mixed by recycled rough aggregate and natural sand or partially recycled fine aggregate and partially natural sand is of higher strength.
