Effect of Roasting on Pore Properties of Fly Ash

Abstract:

Fly ash roasted by different temperature, XRD analysis of fly ash after roasting, specific surface area and pore properties of fly ash roasted before and after were tested. Results showed that roasting influenced significantly on pore properties of fly ash; Specific surface area, pore volume and amount of middle pore of fly ash increased with roasting temperature increased , then reached maximum at 700 °C, and decreased with roasting temperature increased.
