Abstract : Self-compacting concrete or self-consolidating concrete has potential application in many places specially in areas where concrete has to be placed inhighly congested reinforcement. Self Compacting Concrete (SCC) is defined as a category of high performance concrete that has excellent deformability in the fresh state and high resistance to segregation, and can be placed and compacted under its self weight without applying vibration. The higher density and lower permeability of SCC make it susceptible to spalling under severe exposure to fire environment. A mix design procedure for the design of SCC mixes has been developed by modifying the mix proportions arrived from Indian Standard mix design method for different grades of concrete. Flow and strength properties were determined by experimental investigation. The flow properties such as filling ability, passing ability and segregation resistance were found using the Slump Flow, J-Ring and V-Funnel test setups respectively. It was found that the requirements of SCC were satisfied. An attempt has been made to study the effect of elevated temperature on SCC specimens heated from 27ºC to 900ºC under hot condition. The specimens were heated using aElectrical furnace. Mechanical properties such as compressive strength, tensile strength, flexural strength and modulus of elasticity of the refernce and heated specimens were found.The reduction in the compressive, tensile and flexural strengths of SCC specimens were found to be 82.63%, 80.22%and 79.14% respectively for M40 concrete when compared with the reference specimen. Keywords- Self Compacting Concrete, Elevated Temperature, Superplasticizer, Viscosity Modifying Agent, Compressive Strength, Tensile Strength, Flexural Strength.
