'Electric concrete' screens computers

ELECTROMAGNETIC SCREENING around computer rooms with 'electric concrete' has been launched by a UK manufacturer, with claims that the new material is more effective and cheaper than conventional metallic screens.

Developed over 13 years by a team of British inventors, electric concrete is a Portland cement-bound composite containing an electro-conductive blend of carbon and iron oxide. An electro-conductive adhesive is used to attach terminals and bus-bars to individual blocks or to connect bricks and tiles together. The material can also act as a heater.

Manufacturer Flare Group claims the bricks or tiles are much simpler to install than steel, copper or aluminium equivalents, as well as being much tougher. Screen integrity, it claims, is much easier to achieve.

Flare business development manager Richard Gabbitas said that current flow through electric concrete was very uniform, making it a efficient heat emitter. 'There's enormous potential in the use of electric concrete for de-icing applications on roads, airports and other key locations,' he added
