Initial curing to which concrete is

Initial curing to which concrete is subjected, prior to exposure to chloride environment, plays an important role in determining the chloride penetration rate in it, especially atearly ages of exposure [1]. The durability of concrete depends largely on the extent to which the hydrates produced in cement paste fill the space originally occupied by water[2]. Drying of concrete particularly at the concrete surface, caused by a poor curing regime, leads to a restricted hydration in the surface layers and thus higher porosity andpermeability [3]
