Abstract:
Steel reinforcing cables in concrete are protected against corrosion by injecting a carrier fluid and corrosion inhibitors into interstitial spaces between the wires of the cable at a first location along the cable and causing the fluid to pass through the interstitial spaces between the wires of the cable to a second location along the cable. The cable comprises an array of wires confined together and intimately surrounded by a covering material which is engaged with a periphery of the cable so that there are insufficient interconnected spaces between the cable and the covering material to allow passage of fluid longitudinally along the cable outside the cable itself. The method can be used with pre-stressed concrete, with post-tensioned bonded cables and with extruded un-bonded mono-strand cables.

Abstract:
The invention concerns a protective composition obtained by slow polymerisation in situ, after injecting at room temperature into a sheath enclosing the strands of a cable, monomer or prepolymer reagents in the presence of a swelling solvent. The monomer reagents can be identical or different vinyl monomers polymerisable by free radical polymerisation, or bifunctional or trifunctional compounds of two different types reacting mutually resulting in bifunctional or trifunctional polymers, or still mixtures of said compounds. Said composition may further contain an anticorrosive agent. The solvent can be selected among esters of benzoic acid, phthalic acid or aliphatic acid saturated or unsaturated having in the aliphatic chain at least 10 carbon atoms, aromatic or polycyclic hydrocarbons, terpenes and phenolic esters optionally slightly polymerised. The resulting composition has viscoelastic properties which enables it to enhance the cable dampening.
