Title: Old and New Coatings Against Chloride Ingress in Concrete
Author(s): J. Beslac and K. Mavar
Publication: Special Publication
Appears on pages(s): 569-578
Keywords: aging resistance; capillary absorption; chloride ingress;
gas permeability; protective coatings; testing; water vapour diffu-sion
Abstract:The results of laboratory and in situ tests of a number of different types of coatings commercially available in Croatia (polymer-cement, epoxy, acrylic, epoxy-acrylic and epoxy-polyurethane), used for reinforced concrete protection of the KRK bridge, are presented. The tests have been carried on throughout the last ten years. Some coatings like epoxy and polymer-cement were found completely unacceptable for the technical reasons. However, epoxy-polyurethane coatings applied on the concrete finished with the thin layer of epoxy-cement mortar are estimated rather effective. They had high adhesion strength (above 2,0 MPa), very low gas permeability, low capillary absorption, satisfactory water vapour diffusion and satisfactory ageing resistance.
