    Diagnosis and rehabilitation possibilities of real reinforced concrete structure
    (PONTIFICIA UNIV CATOLICA CHILE, ESCUELA CONSTRUCCION CIVIL, 2008) Maria Carvajal, Ana; Araya, Gerardo; Maturana, Pablo
    A diagnosis and rehabilitation study of a reinforced concrete structure is presented in this paper. The Public building was corstructed in 1939, located in marine environment, distant less than I km of the coastal border, in a seismic zone, that for more than one decade has presented pathologies like: cracks, steel corrosion, loosening of concrete coverings and slab deformations. Quantitative analyses of profile chloride and sulphate ions to the concrete in different zones of the building, scanner of the reinforcements with Ferroscan, measurements of corrosion potential, compressive strength and capillary absorption were made. The quantity of chloride and sulphate ions in the concrete exceeded in 1.000% the amount acceptable by Chilean standards: 1,20 kg Cl- /m(3) concrete and 0,600 kg of SO42- /m(3) concrete.
