Adding Water to Concrete Concrete Construction

08-04-2013  The cement (and cementitious materials like fly ash) in the concrete needs water to hydrate and form calcium-silicate-hydrate (C-S-H) which is the crystalline glue that holds the concrete together. The water is chemically bound (consumed) during the reaction with the cement at approximately 25 pounds of water to every 100 pounds of cement.
