Abstract
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.
