Abstract

Provided are a cement composition contributing to long-term strength development, a method of manufacturing the same, and a method of preparing fly ash for a cement composition, the fly ash is capable of maintaining properties as an admixture such as improvement of fluidity or contribution to strength development, and the entire amount of raw material fly ash obtained from a coal-fired power plant or the like as an admixture without removal of coarse powder by classification can be contained. The cement composition comprises cement and fly ash, in which a fly ash content is 30 mass pcnt or lower, and the fly ash satisfies the following Expression (I) in a volume-based particle diameter distribution. in which the amount of an amorphous phase in the mixed fly ash is 55 mass pcnt or higher and 75.1 mass pcnt or lower with respect to the total amount of a crystal phase and the amorphous phase in the mixed fly ash, in which the amount of Fe in the amorphous phase of the mixed fly ash is 3.5 mass pcnt or higher and 10 mass pcnt or lower, and in which a Blaine specific surface area of the fly ash is 3000 cm2/g or higher and 4500 cm2/g or lower, 0.25[(D50-D10)/(D90-D50)[0.47 (I) (In the expression, D10, D50, and D90 represent particle diameters corresponding to a cumulative frequency of 10 pcnt , a cumulative frequency of 50 pcnt , and a cumulative frequency of 90 pcnt in order from the smallest diameter of the fly ash respectively).
