Abstract
A cementitious composition containing metal-coated fibres especially metal-coated carbon fibres in an amount of 0.1 up to 5% by weight relative to the weight of the cement component of the composition. The composition can be used as a conductive layer in a cathodically protected reinforced concrete.
Claims35
In a method of cathodically protecting a concrete structure having an anode and a cathode, the improvement wherein the anode is embedded in a conductive cementitious composition containing metal-coated fibers.
In a cathodically protected metal reinforced cementitious structure having an anode and a cathode with the metal reinforcement functioning as the cathode;
- the improvement wherein said anode is embedded in a cementitious composition containing metal-coated fibers.
A cathodically protected concrete structure comprising a cathode, an anode and a conducting cementitious composition in which said anode is embedded wherein the cementitious composition contains metal coated fibres.
A method of cathodically protecting a concrete structure comprising a cathode, a primary anode and a secondary anode which is a conducting cementitious composition containing metal coated fibres wherein the primary anode is embedded in said conducting cementitious composition.
A cathodically protected concrete structure comprising a cathode, a primary anode and a secondary anode which is a conducting cementitious composition in which said primary anode is embedded wherein the cementitious composition contains metal coated fibres.
A composite reinforced concrete structure comprising a steel reinforcing bar embedded in concrete and a conductor attached to the concrete by means of a conducting cementitious composition containing metal coated fibres.
