Effect of Early Curing Conditions on Permeability of Concrete
The potential effects of damage during early curing of Portland cement concrete have been investigated by measuring the coefficient of permeability. Damage can occur due to temperature gradients caused by heat of hydration or drying shrinkage due to premature loss of water.
