MACt Premix is an easy to use, ‘all in one’ concrete designed especially for making architectural concrete or wherever performance and aesthetics are important. Just add water and glass fibre to make high strength, flowable concrete. Perfect for furniture, bench tops, sinks and vanities etc.
To dose oxide into MACt Premix, you would dose 5% oxide to the cementitious amount in your mix. The calculation is as follows:
Amount of MACt / 2 = Cement (50% of MACx mix)
Cement x 0.05 = Amount of Oxide @ 5%
An example for a 20kg bag would be 20/2 = 10, 10×0.05 = 0.5.
500 Grams would be required for a 20kg bag of MACt premix.
*Please note that some Oxides are made to be does at 2% or 10%, so always refer firstly to supplier instructions.
