Reuse research progress on waste clay brick

Waste clay brick (WCB) is silicate solid waste, its recycling has great environmental and social significance. The application of WCB as recyclable coarce and fine aggregate in concrete and mortar, wall materials, as well as raw material or addition in the production of recyclable cement, has been briefly introduced. The following aspects were emphasized: the research progress of the impact of WCB as supplementary cementitious material on physical mechanics, deformation and durability of cementitious materials; the progress of the function of WCB as environmental materials on eliminating fluorine, ammonia nitrogen and phosphate in waste water; the current research status of the impact of WCB as recyclable aggregate on the mechanics, durability of GRC; the current status of WCB as filler in decorative paints, as filler in rubber plastic materials after being organically modified, as well as in the production of recyclable ancient architectural brick in recent years. The problems in recycling of WCB has also been summarized. (C) 2016 The Authors. Published by Elsevier B.V.
