Abstract: By numerically analyzing the volcanic effects of fly ash, the author points out the method of determining the most reasonable content and exceeding quantity coefficient of fly ash. By that way, we can solve the problem of coordination of the materials used in concrete, and it is practicable in proportion designing of fly ash concrete

Key words: volcanic ash effects, numerically analyzing, the most reasonable fly ash content, exceeding quantity coefficient
