Abstract: Concrete is one of the most extensively used construction material all over the world. Many scientists and researchers are in quest for developing alternate construction material that are environment friendly and contribute towards sustainable development. Huge amount of fly ash is generating day by day which creates the disposal problem and has many environmental issues
Also, building are accidently subjected to fire hazards,during fire the temperature of concrete may go high. Elevated temperature have the potential to induce the formation of cracks in concrete .Similar to cracks in any other material , these cracks can propagate and , over time , result in the compromise of structural integrity , leading to a shortened service life.
In this investigation,The effect of open fire on mechanical strength of fly ash added concrete is studied. The fly ash added concrete is prepared by replacing the cement in concrete by 10% of the cement. The concrete cube specimens of standard size are casted and tested after 28 days of curing. Each concrete cube specimen of normal and fly ash added concrete is exposed to open fire at elevated temperature of (100°C , 200°C, 300°C, 400°C, 500°C, 600°C, 700°C). After temperature regimes the compressive strength is determined for each specimen.
