Experimental Investigation of Penetrating Cracking Self-healing and Leakage in Reinforced Concrete Tank Walls

In order to study the self-healing and leakage characteristics,self-healing performance of penetrating cracks under different constant water head were tested, and water leakage rates were measured when water head declined. The experimental results show that self-healing can occur when there is a positive flow of water through the cracks and a linear relationship exists between liquid leakage rate and decline of water head.
