heal.abstract	Normalized reinforced specimens were placed in 3. 5% circulating sodium chloride (NaCl) solution (25 degree C) under a plus 850-mV anodic charge. At several time intervals on all of these specimens X-ray radiographies were taken focused on the rebars and on the concrete, and the specimens were placed again in the solutions. Because of the direct lowering of the pH in the interface rebar-concrete, the pure electrochemical character of the corrosion overcomes the carbonation, and the concrete cracking is mainly and directly caused by the formation of corrosion products. It was found that during the exposure the permeability of X-rays in the corrosion products decreases because of mechanical stresses. It is possible to follow the evolution of the corrosion products by X-rays and from their permeability to predict the cracking of the concrete caused by the formation of corrosion products.	en
