CONCRETE REINFORCED WITH METAL FIBRE - THERMAL TREATMENT BY MEANS OF ELECTRIC CONDUCTIVITY

BETON DE FIBRES METALLIQUES--TRAITEMENT THERMIQUE PAR CONDUCTIVITE ELECTRIQUE

Details are given of the Joule-effect thermal treatment of fresh concrete containing metal fibres. This treatment appears feasible. If a careful study is made of the electric power used, time of temperature rise and heating, it is possible to use a very low proportion of fibres, together with an energy consumption lower than that used in thermal treatment without fibres. This concrete can be reheated at a later date (hardened concrete), thus facilitating deicing in cold weather. Another application of the electric conductivity of metal fibres is the addition of fine conductive filings in epoxy resin used for the repair of structures with a view to accelerating hardening in cold weather. /TRRL/
