Proper curing is essential for achieving the desired strength and durability of concrete. However, conventional curing methods rely heavily on the continuous application of water, which can be difficult to maintain in many construction environments, particularly in regions facing water scarcity. Self-curing concrete has been developed as an alternative approach to ensure adequate moisture availability within the concrete without the need for external curing. In this research, self-curing concrete was prepared by incorporating suitable self-curing agents into the concrete mix to facilitate internal water retention during the hydration process. Various mix proportions were designed and concrete specimens were cast to evaluate their mechanical performance. The compressive strength of the specimens was determined at curing periods of 7, 14, and 28 days. Here we focused on the design mix of M35 grade of concreate as per IS10262 2019.The results obtained from the experimental investigation were analyzed and compared to the effectiveness of the self-curing mechanism. The findings reveal that the inclusion of self-curing agents improves internal moisture availability and contributes to better hydration of cement, leading to satisfactory strength development around 6-8% then the conventional. This study highlights the potential application of self-curing concrete as a sustainable and efficient alternative to conventional curing practices in modern construction. In this research of self-curing concrete, PEG-400 functions by reducing the vapor pressure of water in the pores of concrete, thereby minimizing water loss due to evaporation. As a result, the concrete retains more moisture for a longer period, which promotes better hydration and improves the development of strength and durability. This characteristic makes PEG-400 particularly useful in regions where water scarcity or inadequate curing conditions are common. M-sand as a fine aggregate, filling the voids between coarse aggregates and contributing to the overall strength and stability of the mix.The particles of M-sand are generally angular and rough in texture, which helps improve the bonding between the cement paste andaggregates. This improved interlocking enhances the compressive strength and durability of concrete. M-sand supports sustainable construction practices by reducing dependence on river sand and minimizing environmental damage causedby excessive sand mining. Due to these advantages, M-sand has become an important component in the production of high-performanceand self-curing concrete used in modern infrastructure projects
