Bentonite is used to reduce earth resistance by providing ground enhancement, which effectively reduces resistance between the soil and the earth electrode (such as copper earth rods or earth mats) by retaining moisture.
Marconite® is a granulated conductive medium designed to replace the conventional aggregate in concrete and thereby provide a permanent medium with good electrical conductivity and high strength.
It can provide a permanent solution to problems in electrical/ constructional situations.
Marconite® concrete is touch dry within hours, but it will be several days before it is 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
PRODUCT DESCRIPTION
Marconite® is a dark grey, granular material that replaces traditional sand and aggregate materials used within concrete mixes. Marconite® is designed, developed and manufactured specifically for use in electrical earthing.
This results in a highly reliable earthing solution with the following unique benefits :
Low resistivity : 0.001Ωm is extremely low when compared to Bentonite’s 3Ωm.
Versatile : suitable for most ground conditions and becomes a permanent, solid structure that it is not prone to shrinking, drying out or being washed away.
Cost effective : it is a permanent solution; there is no need to remove and replace or ‘maintain’ it with additional water / salts every few years in order to achieve the desired earth values.
Chemically inert : is non-corrosive to steel or copper, does not attack cement structures and has a pH within the neutral range.
High strength : can be used as part of the building structure itself and can achieve strengths higher than Grade 25 concrete.
Easy to use : forms a concrete like material that from first pour, achieves a low resistance earth, no need to wait or return to test.
