This study aims to develop a self-healing concrete solution that addresses the issues of high maintenance and repair costs, limited durability, and reduced service life of concrete structures. To achieve this, low calcium Fly Ash and partially replaced recycled aggregate were utilized, resulting in decreased concrete strength. To counteract this issue, macro synthetic fibers were introduced at 0.5 % and 1 %. The samples were then cracked and left to self-heal over a five-week period. The outcomes indicated that incorporating 60 % Fly Ash was the most effective method of healing cracks within the given timeframe. Moreover, the addition of 0.5 % macro synthetic fibers showed substantial enhancement in mechanical properties without compromising workability. This study highlights the potential of self-healing concrete as a sustainable and cost-effective solution to enhance the performance and durability of concrete structures.
