Ground fly ash with a median particle size of 10.5 μm, was used as raw material mixed with NaOH as an alkali activator. Results indicated that ground fly ash gave higher strength geopolymer paste compared to original fly ash. The compressive strengths at 28 days of 20.0–23.0 MPa were obtained. Aydın et al. (2010) showed that grinding ...

Fly ash is a by-product of the power plants burning powdered coal. The suspended noncombustibles during the burning process are subjected to very high temperatures, such that individual mineral grains melt to form individual grains of fly ash.
