REINFORCED CONCRETE: CORRELATION BETWEEN CRACKING AND CORROSION. IN: DURABILITY OF CONCRETE. SECOND INTERNATIONAL CONFERENCE. AUGUST 4-9, 1991, MONTREAL, CANADA. VOLUME II

The object of this work is to determine the relationship between the cracking in loaded reinforced concrete and the corrosion of embedded steel. The test specimens used in this work are three meter long beams, their constructive dispositions and the loadings are in conformity with French specifications (BAEL 83). A salt fog and a gas mixture with same percentage of carbon dioxide and atmospheric air are the two aggressive environments. The authors conclude that a damage of the 'aureole de transition' in the tensile zone of bending beams occurs. The aggressive ions quickly reach the reinforcement through the cracking, whatever their width, and then progress along the embedded tension steel. The influence of concrete cover is clearly proved as well as the aggressive difference of the two conservation environments.
