Improvising the Self-Healing Capabilities of Concrete Using Different Pozzolanic Materials and Crystalline Admixtures

To analyse the self-healing capacities in terms of mechanical performance of the pozzolanic materials, such as, fly ash, metakaolin and silica fume and crystalline admixtures. Pre-cracked concrete cubes with about 0.05 mm width were exposed to four different environmental conditions at different exposure times in order to determine the effect of temperature and water availability on the self-healing potential. After the exposure, the control and tested concrete cubes were evaluated for regained strength, void reduction, corrosion inhibition, damp proofing, relative impermeability and durability. The samples with SF10CA have better cementitious filling and low percentage of voids and water absorption.
