ELECTRICALLY CONDUCTIVE CONCRETE

The article discusses the manufacture of electrically conductive concrete in which conventional sand aggregates are replaced by marconite, a carbon by-product of oil refining. Electrically conductive concrete is produced by conventional mixing methods and when cured has a volume resistivity of 0.5 ohm cm for pre-formed sections or 15 ohm cm for trowelled surfaces. Marconite aggregate is available in four grades to optimize the bulk density of the aggregate to achieve maximum strength and minimum electrical resistance of the hardened concrete. The thermal properties of such a conductive concrete have application in the construction of ice-free runways, bridges and pedestrian precincts. /TRRL/
