Evaluates self-healing performance in concrete with diverse admixtures, suggesting enhancements for durability.
Self-healing concrete presents a cutting-edge approach to improving the longevity and resilience of concrete structures by autonomously repairing micro-cracks and thus creating sustainable infrastructure. This research focuses on evaluating the self-healing performance of M25 grade concrete incorporating crystalline admixture as a self-healing agent, along with mineral admixtures such as fly ash 20 %, ground granulated blast furnace slag (GGBS), 25 %, and alccofine 10 %. The concrete specimens will be subjected to a 28-day curing period. To assess the effectiveness of self-healing, ultrasonic pulse velocity (UPV) and water absorption tests will be used to determine internal damage recovery and healing efficiency. Additionally, compressive strength, split tensile strength, and flexural strength tests will be conducted to analyse the mechanical behaviour of the concrete with different admixtures. The objective of this study is to compare the impact of each mineral admixture on the self-healing characteristics of M25 concrete and to identify the most effective combinations for enhancing structural durability and sustainability. The outcomes are expected to support the advancement of more durable and eco-friendly concrete solutions for infrastructure development.
