新型光催化再生集料透水混凝土的研究

Research of new photocatalytic recycled aggregate concrete

光催化再生集料透水混凝土材料可实现废弃混凝土的资源化利用,使新制备的路面材料具有透水与分解汽车尾气的功能,从而同时解决废弃混凝土处理与大气污染物净化两大难题,并可用于海绵城市的建设。基于光催化降解理论,结合再生混凝土与透水混凝土技术,开展光催化再生集料透水混凝土研究,并给出相关的实验方案与结论,可为路面材料的选择提供参考。

Photocatalytic recycled aggregate concrete （PRAC） has realized the reuse of waste concrete and endows newly-prepared pavements with water permeability and the function of decomposing automobile exhaust. PRAC is able to treat both waste concrete and air pollution at the same time. It shows a great potential in the construction of sponge cites, the research on PRAC with experimental schemes and conclusions is presented. Based on the theory of photocatalytic degradation and technologies of recycled and porous concrete,which can serve as a reference for the choice of pavement materials..
