Indian Concrete JournalSummary: This study investigates the residual strength and microstructural identification of slurry infiltrated fibrous concrete at elevated temperature. The mechanical properties of slurry infiltrated fibrous concrete specimen are found by replacing cement by fly ash and metakaolin in the proportions of 5, 7.5 and 10% by weight of cement. The influence of raised temperature, up to 600°C, on the compressive strength and microstructure of metakaolin and fly ash blended slurry infiltrated fibrous concrete (SIFCON) has been investigated in this study. Two hundred twenty-eight cube specimens of slurry infiltrated fibrous concrete were tested at 20°C and 200-600°C. In this investigation, control specimen, residual compressive strength for 200°C, 400°C and 600°C elevated temperatures as 77, 55 and 20%, respectively, and metakaolin blended slurry infiltrated fibrous concrete residual compressive strength shows 95, 88 and 74%, respectively. Based on the experimental results, this study provides an aid to estimate the mechanical properties of slurry infiltrated fibrous concrete exposed to high temperature.
