Abstract

Modified fly ash (MFA) is defined as FA treated by thermal processing. It is well known that excessive unburned carbon adversely affects the air entrainment performance of concrete. MFA has a consistent LOI of 1% or less. First, the characteristics of unburned carbon in FA and the quality of FA before and after thermal processing were studied, and then, the quality variation of MFA collected periodically were investigated. It was found that MFA with uniformity of characteristics can be produced stably, and one of the obstacles in the promotion of effective utilization of FA seems to have been overcome.
