Marginal materials like laterite aggregate can be used in concrete when performance is more important than strength criteria. A mix design procedure for Laterized Self Compacting Concrete (LSCC) and its performance under elevated temperature has been presented. Test specimens were heated to 200 °C, 400 °C, and 600 °C. The properties of LSCC at fresh and hardened stages were observed. It could be concluded that the type of aggregate and fly ash content prevented the explosive spalling in LSCC even up to 800 °C and the development of surface crack was also delayed up to 600 °C. Further, LSCC could be considered as a substitute fire protection material for conventional concrete.
► A simple mix design procedure has been proposed for medium strength (M20–M40) Laterized Self Compacting Concrete (LSCC). ► Development of surface crack can be delayed up to 600 °C with LSCC. ► Explosive spalling can be prevented up to 800 °C when LSCC is used. ► LSCC could be considered as a substitute fire protection material for conventional concrete.
