Internally cured concrete (ICC) represents a significant advancement in concrete technology, aimed at enhancing durability and extending the service life of structures. This study investigates the development and application of ICC through the incorporation of lightweight aggregate and superabsorbent polymers (SAPs) that retain and release water during hydration. By optimizing the water-to-cement ratio and integrating internal curing agents, we evaluate the effects on hydration kinetics, shrinkage, and long-term performance under varying environmental conditions. Experimental results demonstrate that ICC exhibits reduced autogenous shrinkage and improved resistance to cracking, permeability, and environmental degradation. These enhancements contribute to the longevity of concrete structures, making ICC a viable solution for infrastructure facing severe conditions. The findings underscore the potential of ICC to not only improve the mechanical properties of concrete but also to support sustainable construction practices by reducing maintenance costs and extending service intervals. This research lays the groundwork for further exploration and implementation of ICC in modern concrete applications.
