Water and the Concrete Mix
Water and the Concrete Mix
Water is essential for the hydration of cement particles and controlling the workability of concrete .
Impurities in the mixing water can affect both concrete strength and durability.
Presence of high amounts of chlorides and alkalies may result to corrosion of steel reinforcement and formation of alkali-silica gel with the presence of reactive aggregates, respectively. High amounts of silt or suspended particles in water can negatively impact concrete strength.
ASTM C1602 provides criteria for the acceptance of water to be used in concrete.
