The method for applying a zinc-based anticorrosion layer for reinforced concrete is characterized in that a layer consists of at least two layers, of which the first layer, directly sprayed on the concrete, is made of pure zinc and the second layer sprayed thereon is made of a zinc/alumimum alloy.

Thermally sprayed anticorrosion layer for reinforced concrete and method for making the preparation thereof

The method for improving the corrosion resistance of reinforced concrete coated with a thermal spray coat of metals, especially of zinc or zinc alloys, is effected by electrically connecting said spray coat with the armour and additionally coating it with a polyurethane resin which is applied as a low-viscosity solution in organic solvents.
