Concrete Permeability The provided esfimate for the permeability, "k," e.g., ofthe 28-day cure
concrete of 1 X 10'^ m^ in the equafion v = k (7/ia) • i for water corresponds to about 75 cm/sec for
k in the V = k-i equation shown by Corbitt'. For a k value of 75 cm/sec the concrete would be
very permeable.
