Abstract	This study explores the use of internal curing agents (polyvinyl alcohol, polyethylene glycol 400, polyethylene glycol 6000, super absorbent polymer A, and super absorbent polymer C) in M30 grade concrete to enhance its durability and hydration characteristics. Various dosages of each agent are combined with cement, and the effects are evaluated through compressive strength, rapid chloride permeability, acid attack, salt resistance, and degree of hydration tests. Results demonstrate that optimized internal curing significantly improves concrete performance—showing better compressive strength, greater resistance to chloride penetration, acid, and salt attack, and improved hydration compared to conventional concrete. The findings indicate that selecting proper dosages of internal curing agents can make concrete more durable, especially in water-scarce or aggressive environments.
