The Application Research on Waste Clay Brick in the Cement Concrete

The construction waste has been produced more and more with the rapid development of urbanization and industrialization in China in recent years. The waste clay brick of construction waste named recycled coarse aggregate was mixed with cement concrete mainly by making laboratory experimental study. The clay brick as recycled coarse aggregate was mixed into the concrete at 0%, 20%, 25%, 30 %, 35%, 40%, 50%, 60%, 70%, 80%, 100% and fixed water-cement ratio according to references at home and abroad, which made the C30 standard test blocks, and strictly controlled the variable of the coarse aggregate replacement rate; the slump and 7-day compressive strength were measured, and their performance was compared with that of the standard C30 concrete specimen; the optimum range of incorporation of recycled aggregate would be put forward according to their performance. This result would have a certain significance in waste bricks.
