Corrosion resistance of 10 425 csn/ s185 din prestressing steel with basalt coatings
Original language description
Corrosion damage to conventional prestressing steel reinforcement stimulated by chloride anions has recently caused a critical reduction in the load-bearing capacity and subsequent collapse of several important bridges and footbridges. The use of suitable protective coatings on the surface of the prestressing reinforcement can ensure a significant extension of the service life of these structures. The paper evaluates the corrosion barrier protection of a coating formed from basalt, classified according to QAPF with a high proportion of forsterite and diopsite when hot-dipping on conventional prestressing reinforcement by evaluating the porosity of the coating and exposures in solutions of HCl and NaCl. The roughness and phase composition of two variants of applied basalt coatings, melted at 1260°C on a preheated steel substrate and surface-applied by plasma spraying technology on a cold substrate using a WSP-H 500 water-stabilized plasma torch, were also evaluated. The differences are particularly evident in the increase in the proportion of amorphous silica phases, which ensure almost zero coating porosity and high adhesion even to the plain surface of the metal substrate.
