Investigating self-healing capacity of micro-cracked ECC with different volume of fly ash

Crack is called the intrinsic flaw of concrete that is inevitable for concrete infrastructures during their service life. The presence of crack offer aggressive agent access to pass through, which has a direct impact on durability, therefore resulting in shortened service life. Nevertheless, the influence of crack on the durability can be...

Basic research on the self-healing functions of concrete mixed with fly ash

In recent studies, it has been recognized that concrete deterioration is accelerated by the growth of fine cracks of a few micron meters in width induced by dry shrinkage and/or freezing damage. There have been great expectations for research on concrete that self-heals these fine cracks. Recent research (for example, Taniguchi et al. in the 3rd...
