Concrete has an inherent quantity of water within the mix from the time of batching, typically about 200 litres per cubic metre. The majority of this water is not required to hydrate the cement but is needed to improve the consistence or workability of the concrete to ease handling and placing. The water that is not chemically combined or held by capillary action within the concrete’s pore structure is free to evaporate i.e. dry.
