6. Future Scope The future scope of self-curing concrete is promising, particularly with emergent demands for sustainability, reduced construction complexity and durability. Self-curing concrete is the most ideal material for regions facing water scarcity. Reduction in curing means it reduces site operations and possibly lower the carbon foot print in construction. Hence self-curing concrete paves path to sustainable construction and its performance can be improvised with some of the hybrid inclusion for better scope in future. 7. Conclusions • Previous studies revealed that the durability of self-curing concrete by means of adding Super Absorbent Polymers (SAP) and Polyethylene Glycol (PEG) have shown promising results. • Self-curing concrete incorporated with SAP and PEG demonstrated better curing efficiency compared to conventional concrete. The materials effectively absorbed and retained water within the concrete matrix, facilitating continuous hydration and reducing moisture loss. • The presence of SAP and PEG in self-curing concrete resulted in reduced drying shrinkage and minimized cracking. The materials helped to maintain a more uniform moisture distribution throughout the concrete, mitigating the development of internal stresses that typically lead to shrinkage cracks. • Self-curing concrete exhibited improved strength development over time. The sustained hydration process facilitated by SAP and PEG allowed for continued cement hydration, resulting in denser and stronger concrete with advanced compressive forte. • The addition of SAP and PEG not significantly affected the workability. In fact, it was reported that the materials improved workability by reducing water loss. Self-curing concrete also exhibited smoother surface finishes due to reduced cracking and shrinkage. • Further research and long-term monitoring are recommended to validate the findings and optimize the formulation of self-curing concrete for different applications and environmental conditions.
