A Study On Behaviour Of Normal Strength Concrete And High Strength Concrete Subjected To Elevated Temperatures

Abstract

Cement concrete is a complex mixture of different<br> materials. Behaviour of concrete depends on its mix proportions and<br> constituents when it is subjected to elevated temperatures. Principal<br> effects due to elevated temperatures are loss in compressive strength,<br> loss in weight or mass, change in colour and spall of concrete. The<br> experimental results of normal concrete and high strength concrete<br> subjected elevated temperatures at 200°C, 400°C, 600°C, and 800°C<br> and different cooling regimes viz. air cooling, water quenching on<br> different grade of concrete are reported in this paper.
