Why is it important that during the first few days of the curing of concrete the
evaporation of water from its surface be prevented or reduced?
It is important to prevent or reduce rapid evaporation of water from the surface of
concrete during the first few days of the curing so that the desired strength and durability
is achieved. The compressive strength of concretes made with ASTM-type cements
continues to significantly increase for time periods on the order of a month or a year.
Hi
As well known the evaporation of water from the concrete will leave voids and these voids are not favorable, as well as during the mixing design (the water amount is measured in order to hydrate most of dry cement particles) and the evaporation of water will prevent the dry cement particles from getting the required water.
