The effect of temperature on Self- compacting concrete (SCC) is investigated in this paper. SCC is a high- performance concrete that flows under its self-weight with adequately filling all the voids without any segregation or bleeding. It is a revolutionary development in the area of concrete admixtures. In this paper effort has been made to present the effect of temperature on compressive strength of self-compacting concrete produced by replacing ordinary Portland cement with 15% fly ash and then treated water quenched. Compressive strength of concrete is the major property which identifies the quality of concrete produced. Generally the compressive strength test is performed on concrete samples at room temperature to determine the developed strength of concrete. In order to study the effects of high temperatures on compressive strength of SCC, cubical specimens (100x100x100 mm) were heated at high temperatures (150˚C, 200˚C, 250˚C and 300˚C) for varying exposure duration (11/2, 2, 21/2 and 3 hours) . The results obtained were compared with the corresponding properties of NVC (Normally Vibrated Concrete).
