• Abstract:

  Some aspects of the behavior up to failure of reinforced and prestressed concrete elements under long-term loading (10 to 12 years), in different aggressive environments, are presented. Lightweight and normal concrete elements were exposed both in aggressive environments (chloride and nitrate pollution) and in natural environments (urban and sea). Long-term loaded elements presented cracks with a maximum width of 0.15 to 0.20 mm (0.0589 to 0.0786 in) for reinforced concrete beams and 0.05 to 0.10 mm (0.00197 to 0.00393 in.) for prestressed beams.)After 10 to 15 years, tests were performed to establish the influence of long-term aggressivity and cracking pattern on concrete durability and safety of the elements under study.
