Self-curing concrete: a state-of-the-art review
In self-curing concrete, the availability of additional internal water that was not mixed in, causes the cement to hydrate. Due to the fact that concrete cures from the inside out, self-curing concrete helps to reduce water waste. Concrete that cures on its own totally eliminates the risk of diminished strength and durability
