Abstract The hydration process contributes a significant role in concrete production. Cement is manufactured using calcium carbonate (CaCO₃) from limestone with silica and alumina from clay or shale. The calcium-silicate-hydrate (C-S-H) gel formation is fundamental to enhance binding properties of cement. This reaction needs water and is subjective by the presence of calcium oxide (CaO), making proper water curing essential for strength development. Up until the point at which hydration is complete, water curing is crucial. The current work examined the usage of internal curing agents in concrete viz. Super Absorbent Polymers (SAP) and Polyethylene Glycol (PEG) as in order to circumvent the current curing procedure. Self-curing concrete with PEG and SAP reduced autogenous shrinkage from the perspective of durability, and a decrease in the water-cement ratio primarily eliminated drying shrinkage. It reduces shrinkage, creep, and micro cracks in the concrete structure, boosting its strength and decreasing permeability. As a result, self-curing concrete made with PEG and SAP has the potential to function as a self-curing agent in contemporary concrete with longer lifespan than regular concrete. © 2025 The Authors.
