Abstract: The present work deals with results of an investigation of High strength Metakaolin concrete at the high temperature. The Metakaolin is varied from 0 to 15% by replacing cement at the interval of 3% by the weight of cement. The optimum percentage of the Metakaolin in concrete is obtained by the compressive test carried on the concrete. To study the effect of elevated temperature the specimens are put in the Hot Air Oven at the varying temperature of 2000C, 4000C and 6000C also the duration is varied. The cube of the size 150mm x 150mm x 150mm for compression strength and the beam of the size 150mm x 150mm x 700mm for the flexural strength. The cylinder of the size 150mm diameter and 300mm height for the split tensile test. The workability measured with the slump cone. The weight and dry density also calculated. The objective of this work is to do the comparative study of high strength OPC concrete and steel fibre reinforced metakaolin concrete at different temperatures of 2000C, 4000C and 6000C. The effects of elevated temperature on the high strength concrete materials are observed and their performance compared to the normal strength of concrete.
