Abstract
Volume change of super high strength and high performance concrete with different binder-aggregate ratios and different curing conditions were investigated in this paper, and the volume changes of cement paste and mortar were also tested. The results indicated that the change of cement paste was much higher than mortar and concrete under the same curing conditions；the curing condition has a obvious influence on the volume change; there was a moisture swell for the water curing concrete; the specimens with limestone powder have smaller volume change than those specimens without limestone powder. The volume change mechanism was explained, and the effect of limestone powder on the volume change was also discussed.
