CONCRETE Optimizing the Use of Fly Ash in Concrete

Figure 2. Schematic layout of a coal-fired electrical generating station (Sear 2001). In the production of fly ash, coal is first pulverized in grinding mills before being blown with air into the burning zone of the boiler. In this zone the coal combusts producing heat with tempertures reaching approximately 1500°C …
