Effect of Elevated Temperatures on Properties of Ultrafine Slag Concrete – A Review

Abstract

Concrete is a versatile engineering material used in the construction industry. It is usually subjected to elevated temperature in an accidental fire, or industrial installations fire prolonged duration known as Sustained Elevated Temperature. The change in properties of concrete due to elevated temperature depends on many factors like maximum temperature, duration, concrete grade, etc. The present literature gives the changes in concrete considering maximum temperature, and the results are based on time-temperature curves. It does not reveal much information on the duration effects of temperature
