using fixed concrete slump method,the carbonation resistance of concretes with high-volume fly-ash and ground granulated blast-furnace slag had been studied, and make an approach to size- effect .The results show that the more fly-ash joined in,the more carbonation depth is deeper . The carbonation resistance of concretes with high-volume fly-ash and ggbs is better than only with high-volume fly-ash’s. Size effect on carbonation depth of concretes is also important . Carbonation depth will become deeper as soon as the block size improving .and the early improvement is bigger than the late .The more concretes with high-volume fly-ash and ground granulated blast-furnace slag,the size-effect on carbonation depth of concretes will be more evident.

To improve the application of low-quality aggregates in structural concrete, this study investigated the effect of multi-purpose mineral admixtures, such as fly ash and ground granulated blast-furnace slag, on the performance of concrete. Accordingly, the primary performance of low-quality recycled aggregate concrete could be improved by varying the replacement ratio of the recycled aggregate and using appropriate mineral admixtures such as fly ash and ground granulated blast-furnace slag. The results show the potential for the use of low-quality aggregate in structural concrete.
