Abstract :

The intriguing idea of self-healing concrete plays a key role in improving the durability of concrete. This study compares self-healing concrete to its conventional counterparts in order to examine the effects of crystalline coatings and admixtures. The flexural and compressive strengths, water absorption, and fracture bridging of four concrete compositions were investigated. A variety of experiments were used, both destructive and non-destructive. Using microstructure and crack-healing tests on injured specimens, the mixtures' ability to repair themselves was assessed. Fresh state properties were measured using slump cone and air content tests. The outcomes demonstrate how crystalline mixtures may be used to treat concrete injuries. Compressive and bending strengths of self-healing mixes were marginally increased by increasing additive doses. These mixtures showed evidence of increased durability in the form of repaired gaps, reduced water absorption, and an enhanced microstructure.
