For the application into Runyang Bridge over Yangtze River,three proportions of concrete mixtures mixed without or with fly ash have been studied in detail and analyzed contrastively in this paper.Compared with the reference concrete without fly ash,the concrete for prestressed box beam with 12 percent fly ash as the substitution of cement had better properties.The results show that fly ash could improve the workability of the concrete mixture obviously,increase the durability at a certain… CONTINUE READING
