Marconite® is also available in the form of a ‘premix’. This is a standard 25Kg poly sack which contains pre-weighed amounts of Marconite® and cement powder in the correct ratio to form the preferred concrete.
With the addition of 5 litres of water, each bag can then be mixed independently and used without the need to carry additional cement powder. Utilising Marconite® Premix reduces the possibility of incorrect mixing as work crews only carry one type of bag thus preventing on site confusion.
However, Marconite® Premix contains Portland cement powder which is hygroscopic resulting in limited shelf life. As a result this product is only available for sale within the UK and must be used within 6 weeks of purchase.
