Carbonation resistance of concrete with fly ash as fine aggregate

In order to investigate the carbonation resistance of concrete with fly ash as fine aggregate (CFA), the rapid carbonation test was conducted to explore the influence of the curing age, water-to-cement (w/c) ratio, fly ash replacement rate and the activator on the carbonation depth. The experimental...
