Abstract: The curing of concrete has a paramount influence on strength and durability of concrete structures which are exposed to an aggressive environment or which may suffer from steel rebar corrosion. Curing should also ascertain the hydration of cement throughout a concrete member in order to achieve the designed strength.
As high strength concrete is concerned there may be some conflicting aspects with respect to curing: firstly, the water-cement ratio is low and hydration proceeds quickly, i.e. the water is bound before the removal of the mould; secondly, the structure of the hydrated cement paste is dense and thus water evaporation is low; thirdly, due to the dense structure, water from outside cannot reach the interior of a concrete member. Whether these expectations are correct or not has not been verified yet as both the literature and the site data are controversial.
To find out more about the effects of curing on water loss and the strength and permeability of high strength concrete a research project was established.
