        abstract = {Adequate curing is essential for ensuring proper hydration, microstructural development, and long-term performance of concrete; however, conventional curing methods are often ineffective in water-scarce environments. This study investigates self-curing concrete using polyethylene glycol (PEG) as an internal curing agent and fly ash as a supplementary cementitious material. PEG enhances internal moisture retention by reducing surface tension and sustaining hydration, while fly ash contributes to secondary pozzolanic reactions, improving strength and durability.
Concrete mixes of M20 grade were prepared with varying PEG dosages (0.2–0.9%) and fly ash replacement levels (5–20%). Mechanical properties, including compressive and flexural strength, were evaluated and compared with conventionally cured concrete. Results indicate improved hydration, reduced shrinkage, and enhanced strength in self-curing mixes. The optimal combination of 0.7% PEG and 10% fly ash demonstrated superior performance. This approach promotes sustainable construction by reducing water demand and cement consumption.},
