(PDF) South Africa Fly Ash and Materials

South Africa only produces Class F Fly Ash but it was proved in studies around the world that due to that it is a pozzolanic material, it reacts with lime/cement to form cementitous compounds .

The amount of fly ash available in South Africa (20 million tons) significantly exceeds cement clinker capacity (10 million tons). Driven by the need to enhance the properties of fly ash the finer more reactive fraction was initially recovered from the last 3 fields of the array of electrostatic precipitators.
