The Experimental Research on the Effect of Age on Bond Behavior between Deformed Bar and Shale Ceramic Concrete

In this paper, the effect of age on bond behavior between deformed bar and shale ceramic concrete was analyzed by four groups of pull-out tests with different age. And three reinforced concrete pull-out tests used for comparative analysis were prepared at the same time. We obtained a series of experimental data and based on these data a more accurate formula was summed up. This conclusion is important for further study on bonding properties of ceramic concrete and has a high value in guiding the actual construction.
