Abstract

Disclosed is a cement composition that retains properties as a mixing material such as improving fluidity and contributing to a strength development, said cement composition being capable of using all of the raw material fly ash obtained from a coal-fired power plant, without having to classify out the coarse powder, and also being capable of contributing to long-term strength development. The cement composition comprising: cement; and a fly ash, wherein a content of the fly ash is between about 5 and 30 mass% or lower, and the fly ash satisfies a specific predetermined volume-based particle diameter distribution of Expression (I) (as defined herein), an amount of an amorphous phase in the fly ash is between about 55 and 75.1 mass% with respect to the total amount of a crystal phase and the amorphous phase in the fly ash, an amount of Fe in the amorphous phase of the fly ash is between about 3.5 and 10 mass%, and the Blaine specific surface area of the fly ash is between about 3000 cm2/g and 4500 cm2/g. Also provided are methods for producing the cement composition, and for producing fly ash for the cement composition.
