Abstract:
Concrete structures present in areas of high aggressiveness, such as areas near the coast, are prone to attacks by aggressive chemical agents, such as chloride ion attack, resulting in corrosion of the frame and consequent concrete degradation and its breakdown, structure functionality committed. In order to study the behavior of the concrete in the aggressive environment, the methodology used was the accelerated process of aging of the concrete, with a maximum period of 120 days, and parallel to this process axial compression tests were performed at the ages of 7, 28, 60. , 90 and 120 days, as well as tests of chloride, conductivity, total dissolved solids, salinity, in the same period. Through the tests, it is possible to observe the effect of the chlorides in the concrete structures, but in an incisive way in the reinforcement, already the concrete presented a pathology that does not take into account that is the efflorescence, and its performance became very visible after the period of 60 days
