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 4 Kg of total mix, i.e.:
3 x 25 Kg bags of Marconite
1 x 25 Kg bag of Cement
25 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 application requires, but this will affect the concretes final compressive strength and the drying 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.
