means that the steel is protected from corrosion in the absence of damage to the concrete cover to the steel or aggressive chemicals. At this pH value a passive film forms on the steel that reduces the rate of corrosion to a very low and harmless value. Thus, concrete cover provides chemical as well as physical protection to the steel.
