In Japan, approximately 7.6 million tons of coal ash is produced from thermal electric power plants in fiscal 1999. To protect the environment and make effective use of resources, methods should be established for effective and large quantity use of coal ash. In this study, mix proportion theory of concrete containing large quantity of coal ash was discussed. As a result, the formula that was presented for the concrete containing coal ash with constant portland cement content was shown to be applicable to the concrete containing coal ash with constant powder content. Next, the new method and its formula for the concrete that always performed the same compressive strength to the portland cement only concrete with the appropriate combination of the cement and coal ash content were shown.
