Normal water, typically referring to potable or tap water, is a fundamental component in the production of cement and concrete. It is essential for the hydration process of cement, where water chemically reacts with Portland cement to form the paste that binds aggregates together to form concrete. The quality of water used in concrete mixtures can significantly affect the properties of the final product, making it crucial to understand its role, especially under severe environmental conditions where the durability and strength of concrete are tested.
