Earth Compound

Product Information:

Compound is a granulated conductive medium designed to replace the conventional aggregate in concrete and thereby provide a permanent medium with good electrical conductivity ,protective earth and high strength.

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

Compound concrete is touch dry within hours, but it will be several days before it is fully cured.

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

Features:

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

Low resistivity, especially when compared to Bentonite
Does not rely on moisture to conduct electricity
No seasonal variation – does not rely on water to conduct, does not shrink
Does not require maintenance
Chemically inert and non-polluting – non-corrosive to steel and copper, it does not attack cement structures. Its PH is within the neutral range
Environmentally safe – it does not dissolve or dissipate like other chemical enhancers such as caustic soda, salt and acid based products
Easy to use – forms a concrete like material that can be poured as a slurry and in some situations, used dry
Acts as a theft deterrent
High strength – can be used as part of the building structure and achieve strengths of grade 25 concrete
Synthetic material manufactured specifically for earthing applications

More Information:

a) Compound is the ideal solution for use in problem earth situations
In areas of poor soil conductivity (high resistivity) – e.g. rocky areas, sandy soil etc.
b) In conjunction with lattice mats/plates (where the earth electrodes cannot be deep driven)
c) Where space is limited

MIXING INSTRUCTIONS:

Plain Compound:
3:1 mix Compound/cement by weight plus 1 litre of water per 4kg. (ie 3 x 25kg bags of Compound, 1 x 25kg bag of cement, 6 litres of water.)

It is possible to vary the ordinary portland cement and water content to suit local conditions, but this will affect the performance of the finished concrete.

Compound Premix:
Compound have already been mixed, simply add 6 liters of water per 25kg bag of Compound Premix.

When mixed as above, relatively dry material is formed. Water content can be adjusted as the application requires, but this will affect drying times and resultant compressive strength. Typically, the mix is touch dry within hours but not fully cured until after several days.

Density:

Pure dry Compound is approximately 1,000kg/m3 (40 x 25kg bag per one cubic metre)
Dry Compound pre-mix is approximately 1,250kg/m3 (50 x 25kg bags per one cubic metre)
The fully hardened density of Compound concrete, mixed as per instructions, is 1,500kg/m3

We recommend plain Compound for export markets.

For installing lightning earthing system applications, We recommend the use of Copper earth electrode systems due to their inherent low resistivity and corrosion resistance.

Materials used in earthing systems must be able to:
