摘 要：IN this artucke the high strength micro-expansive concrete that has been applied on big-diameter and long-span steel arch bridge is researched. The applications show that the concrete has some merits , such as good fluidity, low bleeding ratio and no segregation, low slump loss, high early strength and high later strength, micro- expansion etc.
