Rapid increase in greenhouse gas induces mischievous impact on environment. In this study, carbon dioxide emission can be reduced to some extent by replacing some amount of cement with corn cob ash. The performance of concrete at high temperature was also studied. This paper investigates the effect of elevated temperature on strength property of ordinary concretes of grade M25, containing Corn Cob Ash (CCA) at various replacement levels of cement. The cube samples were subjected to high temperature of 1500C, 3000C, 4500C and 6000C for 2 hour duration in a muffle furnace. The samples were tested for compressive strength after air cooling to the room temperature. It can be seen that at normal temperature, compressive strength of the concrete decreases as the CCA content increases. The compressive strength of concrete increased significantly for all the mixes including control mix when the temperature was raised to 3000C. The recommended maximum replacement content of cement with CCA and elevated temperature was 10% and 3000C respectively.
