DEVELOPMENT OF TEST PROCEDURES FOR SURFACE TREATMENTS OF REINFORCED CONCRETE FOR THE REPAIR AND PREVENTION OF CORROSION DAMAGE

ENTWICKLUNG VON PRUEFVERFAHREN FUER OBERFLAECHENBEHANDLUNGEN VON STAHLBETON ZUR SANIERUNG UND VERHINDERUNG VON KORROSIONSSCHAEDEN (C 95 432)

TEST METHODS ARE TO BE WORKED OUT WHICH ALLOW THE DURABILITY AND CORROSION PROTECTION ACTION OF VARIOUS MEASURES TO BE EVALUATED. PLAN OF WORK: (1) DEVELOPMENT OF SUITABLE SHORT TERM LABORATORY TESTS TO DETERMINE DURABILITY AND CORROSION PROTECTION; (2) DETERMINATION OF THE INFLUENCE OF SURFACE TREATMENTS ON RESISTANCE TO CO2 DIFFUSION IN THE CONCRETE SURFACE; (3) WORKING OUT OF A METHOD OF CALCULATING THE EFFECTIVENESS OF THE CO2 RESISTANCE.
