    Hydration is the process by which portland cement, in the presence of water, becomes a bonding agent, evolving heat. In the water-cement paste, the silicates and the aluminates form the products of hydration. With time, they produce a firm and hard mass. The hydrated cement paste is stable in contact with water.
