The invention relates a cord for the reinforcement of a cementitious matrix. The cord comprises number of coated metal filaments twisted together to form a cord. The cord shows cross-sections, whereby three or more of the filaments form a closed sub-structure having a void in the middle of the three or more filaments. The cord further comprises a protective compound whereby the protective compound is at least present in said void. The protective compound gives the coated metal element cathodic protection. The invention further relates to a structure comprising a number of cords such as a knitted, a braided, a welded or a glued structure. Furthermore the invention relates to a cementitious matrix reinforced with a cord according to the present invention and to a method to inhibit hydrogen gas evolution at the interface of a cord embedded in a cementitious matrix.

Cord for reinforcement of a cementitious matrix

The invention relates to a reinforced structure comprising a cementitious matrix and zinc coated metal elements. The structure comprises at least at the interface of the zinc coated metal elements and the cementitious matrix a compound selected from the group consisting of the imidazoles, the triazoles and the tetrazoles. The invention further relates to a zinc coated metal element for the reinforcement of a cementitious matrix and to a method to inhibit hydrogen gas evolution at the interface of zinc coated metal elements embedded in a cementitious matrix.

A wire for external exposure, i.e. without chemical binding with a polymer or rubber matrix. The wire has a steel core, a nickel sub-coating and a zinc or zinc alloy top coating above the nickel sub-coating. The steel core has a carbon content exceeding 0.20%. The wire is in a work-hardened state by drawing or rolling. The wire has an excellent corrosion resistance and provides an excellent barrier against hydrogen. Preferable uses are wires in off-shore applications.

A corrosion inhibiting composition containing a carrier of an oily or waxy type together with active components including at least one corrosion-inhibitor of the azole-type and a co-corrosion-inhibitor, together with optional water repellants or certain alcohols alone or in admixture. The compositions are suitable for protecting from corrosion steel wire or steel cord composed of several steel filaments.
