Abstract

Concretes containing mineral admixtures are used extensively throughout the world for their good performance and the effects of high temperatures on such concrete are also due on its behaviors. Therefore an experimental study has been done to study the compressive behavior, physicochemical qualities of concrete exposed to high temperatures. The investigations were directed on ordinary Portland cement concrete cubes supplemented with 10% and 20% fly ash by weight of concrete. The cubes were along these lines presented to hoisted temperature in furnace under temperature scope of 100-600 °C and tried previously, then after the fact heating by ultrasonic testing and direct compression testing. The cubes tests were checked under differential calorimeter for watching the progressions under various lifted temperature. The result indicates that there is a drastic reduction in compressive strength occurred at temperature beyond 400 °C and higher losses were occurred with increase amount of fly ash in concrete.
