- Hydration is the chemical reaction between cement and water that hardens concrete. - Proper curing requires maintaining moisture content. - Rapid evaporation leads to incomplete hydration, reduced strength, increased permeability, and potential cracking.
The surface of the concrete structure of a new construction is covered with straw/gunny bags by wetting. This is done to :
