Experiments on the development of compressive strength and static and dynamic Young’s moduli were performed by the following mix proportions of concrete: the first uses different types of Portland cement without fly ash (FA) with a water-cement ratio of 45%, keeping at different curing temperatures; the second partially use FA in place of the cement, with the other conditions same as above; the third uses only blast furnace cement B instead of Portland cement. With these specimens, we comparatively examined in terms of temperature adjusted concrete age, how the mechanical properties change with the use of cement only, FA replacement for cement and with variation in curing temperatures. As a result, it was confirmed that the replacement of cement by fly ash enhanced the long-term mechanical properties of concrete regardless of the curing temperature applied in this experiment. |
