What is heat of hydration in concrete?
The term hydration is involved water.When water is added in dry cement a chemical reaction occurs, in which heat comes out. Actually the reaction is exothermic. This heat is called the Heat of hydration.
To manage the heat of hydration CURING is requared. We need to add some extra water in concreat or dry cement. Becouse some water evoporate in atmosphere so reation elements used water present in concrete that why cracks develop on surface. These cracks are called shrinkage cracks.
Heat of hydration is responsible for development of shrinkage cracks on surface of concrete.
