再生骨料混凝土技术及其研究现状

Introduction of recycled aggregate concrete technology and current research situation

我国是一个资源短缺、粗放经营的资源消费大国,经济增长越来越受到资源和环境的约束。从节约资源、改变粗放营生产方式、走可持续发展道路角度考虑,对再生骨料混凝土的研究和利用非常必要。从再生骨料混凝土的定义入手、结合国内外的研究现状对再生骨料的加工方法以及相应的水玻璃溶液处理技术做相关介绍。对再生骨料混凝土进行LCA评价(寿命周期评价),提出了高强高性能再生骨料混凝土。

It is necessary and indispensable to focus on the research and utilization of recycled aggregate concrete and development on a sustainable way for sources-saving and changing production mode.The processing method of recycled aggregate and correspondent technology on soluble glass solution are introduced, based on definition of recycled aggregate concrete and its domestic and abroad research situation.The LCA （Life Cycle Assessment） evaluation towards recycled aggregate concrete is presented.And the definition of high strength recycled aggregate concrete is formed finally.
