Marconite: Granulated Conductive Medium

Marconite® is a granulated conductive medium designed to replace the conventional aggregate in concrete and thereby provide a medium with good electrical conductivity and high strength.

It can provide a permanent solution to problems in electrical / constructional situations.


Marconite® is a dark grey, granular material that replaces traditional sand and aggregate materials used within concretes mixes. It should be mixed in the ratio of 3 parts of Marconite® to 1 part cement by weight with the addition of 1 litre of water per 5 Kg of total mix, ie

– 3 x 25 Kg bags of Marconite
– 1 x 25 Kg bag of Cement
– 20 litres (25 Kg) of water

When mixed as described above, it forms a relatively dry material with an ‘as poured’ density of around 1300 Kg/m³. The water content may be adjusted as the applica-tion requires, but this will affect the concretes final compressive strength and the dry-ing times accordingly. Typically Marconite® concretes are touch dry within hours but can be several days before being fully cured.

Marconite® is chemically inert with very low soluble sulphate content. It can be used with all conventional types of cement, as well as most proprietary resin-based cements, adhesives and gypsum plasters.
