Abstract
Dam concrete with highly replaced fly ash (Fa) based on ordinary portland cement (OPC) was investigated, in which the study of the characteristics of strength, adiabatic temperature and durability was performed. In spite of highly replaced Fa, it's early and long-term strength were higher than those of Dam concrete with moderate heat portland cement which Fa-replaced-percentage was 30% (MPC30%). Compared with MPC30%, adiabatic temperature of these Dam concrete with the same σ91 were lower and the durability against freezing-thawing repetitions and carbonation were almost same. The C/S ratio of OPC40, 60% were a little lower than that of OPC30%, but it was almost same.
