PROBLEM TO BE SOLVED: To provide a fly ash cement production process by which the mixing ratio of fly ash to cement can be enhanced with out adversely affecting the characteristics of the resulting fly ash cement, such as strength and flowability, and accordingly the fly ash reutilization efficiency can be enhanced to reduce the amount of fly ash disposed as industrial waste. SOLUTION: This production process for producing fly ash cement by mixing Portland cement with fly ash involves mixing Portland cement with a fly ash blend obtained by blending fly ash spherical particles and a fly ash ground material together in a blending ratio by weight of the (fly ash spherical particles):(fly ash ground material) of 7:3 to 3:7.
