碎砖骨料再生混凝土砌墙砖的抗冻融试验研究

Experimental research on freeze-thaw resistance property of recycled brick aggregate concrete wall bricks

试验用50%、60%、70%再生碎砖粗骨料替代天然碎石粗骨料,配置碎砖骨料再生混凝土,经成型获得碎砖骨料再生混凝土砌墙砖,进行冻融循环试验,探究碎砖骨料再生混凝土砌墙砖的抗冻融性能及其影响因素,为进一步探究高取代率碎砖骨料再生混凝土砌墙砖提供参考数据。

In this experiment, 50%, 60% and 70% recycled brick aggregate （RBA） replaces the traditional coarse aggregate to obtain the recycled brick coarse concrete. After shaping in the special design ,it hits the target of recycled brick aggregate concrete wall bricks. In the freeze-thaw cycle test,it research es the freeze- thaw resistance property of the brick, which provides some reference data for the further research on the brick of high replacement rate of RBA.
