Effect of Variation of Elevated Temperature on Compressive Strength of Metakaolin Concrete: Literature Study

Abstract

It has been found that high early temperature has negative impacts on later compressive strength of concrete. Some researchers investigated the adverse effect on long term strength of concrete due to high initial temperature. The effect of temperature on different properties of concrete is considerable and remained the subject of research activities of a lot of researchers. Different investigators moved in different ways and investigated temperature effect by changing different parameters such as w/c ratio; mix ratio, early change in temperature etc. The objective of this literature work is to provide an overview of the effects of elevated temperature on the behavior of Metakaolin concrete materials and structures. In meeting this objective the effects of elevated temperatures on the properties of concrete constituent materials and concretes are summarized. The effects of elevated temperature on high-strength concrete materials are noted and their performance compared to normal strength concretes.
