Abstract
Provided are fly ash, a cement composition containing the fly ash, and a method for preparing fly ash, the fly ash being capable of suppressing deterioration in fluidity to improve workability and suppressing color unevenness. In the fly ash, a content of particles having a particle diameter of 45 æm or more measured by a Laser diffraction particle size analysis method is lower than 38 vol pcnt , and a content of particles having a particle diameter of less than 5 æm measured by the analysis method is 12 vol pcnt or lower. In addition, the cement composition comprises the fly ash and cement.
