Abstract

Provided are: a fly ash in which reduction in fluidity thereof can be inhibited and the workability thereof can thereby be improved, and the occurrence of color unevenness thereof can be inhibited; a cement composition using the fly ash; and a production method for the fly ash. This fly ash is characterized in that the contained amount of particles having a particle size of 45 μm or more as measured by a laser diffraction scattering particle size distribution measurement method is less than 38 vol%, and the contained amount of particles having a particle size of less than 5 μm as measured by the aforementioned measurement method is 12 vol% or less. This cement composition contains said fly ash and cement.
