For
further information on Marconite, please contact the Furse sales
office. A separate data sheet is available. Marconite is a registered
trademark of Marconi Communications Ltd., and is manufactured by PMC
Holdings Ltd. - Conductive Products Division.
Marconite is a unique product, developed by Marconi Communications Ltd.
Certain
ground conditions make it difficult to obtain a reliable earth
resistance, whilst particular installations may require a very low
resistance. In such cases, Marconite provides a convenient and
permanent solution.
By adding Marconite in place of sand and aggregate, to cement, a conductive concrete is
formed. This electrically conductive medium has many applications in
the electrical/construction industry, including RF and microwave
screening, static control and of course earthing, for which itwas
specifically developed.
When
used as a backfill for earth electrodes, Marconite impregnated concrete
greatly increases the electrodes surface area thus lowering its
resistance to earth.
No other product can offer the same benefits as Marconite in earthing applications.
Moisture retaining clay

Used
as an earth-electrode backfill to reduce soil resistivity by retaining
moisture. The clay consists largely of sodium montmorillonite, which
when mixed with water swells to many times its dry volume. It has the
ability to hold its moisture content for a considerable period of time
and to absorb moisture from the surrounding soil (e.g.from rainfall).
