摘要
The use of fly ash is in harmony with the concept of sustainable development. This paper discusses the effect of replacing ratio of fly ash (FA), ambient relative humidity, temperature, curing age and w/c on carbonation of concrete made with low-volume FA. The process was accelerated in artificial carbonation laboratory by controlling 20% concentration of CO2, temperatures from 20 degrees C to 60 degrees C and 30%-70% relative humidity. The contrastive results show that the carbonation model for predict carbonation depth has a nice performance.
