再生混凝土性能的研究与开发

The Research and Exploitation of the Natural Capacity of Regenerative Concrete

旧建筑物拆下来的废料中废混凝土约占34%,目前还没有得到利用,不仅带来环境的污染,又造成资源的浪费。为此,本文对废混凝土破碎物代替粗骨料配制的再生混凝土性能进行了研究。研究表明,用废混凝土培植的再生混凝土拌合物粘聚性,保水性好,流动性可满足施工要求。建筑物中低强度混凝土可用再生混凝土代替,并能取得较好的环境经济和社会效益。

The waste concrete is about34%of the total materials pulled down from an old construction.At present,it is not used yet.It not only pollutes the environment,but also causes the waste of resources.This paper makes a research into the substitution of the waste concrete for the regenerative concrete mixed with rough aggregate.The study proves that the stirred mixture of the regenerative concrete made from the waste concrete has good glutinosity,which can meet the construction requirement for its good water-retaining and flowing nature.Low strength concrete can be replaced by regenerative concrete.In this way,better environment and social profit can be achieved.
