Performance Evaluation of High Strength Steel Fiber Reinforced Metakaolin Concrete at Elevated Temperature

The present work deals with results of 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 furnace at the varying temperature from 2000C to 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 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 provide an overview of the effect of elevated temperature on the behaviour of metakaolin concrete material. The effects of elevated temperature on the high strength concrete materials are observed and their performance compared to the normal strength of concrete.
