BEHAVIOUR OF M20 GRADE CONCRETE AT DIFFERENT TEMPERATURES

The structural element subjected to high temperatures lead to significant losses due to the reduction in the strength of the concrete .with the mode toward urbanization, rate of construction and hazards related to it has increased to high extend. One such major source is fire accidents. Structure can undergo fire accident, but because of this the structure cannot be denied neither abandoned. To make a structure functionally viable after the damage due to fire has become a challenge for the civil engineering community. The problem is where to start and how to proceed. The root for such problem lies in the strength parametric study of component material that is used in construction industry. One such major item is concrete, which have very distinct chemical and physical properties because of its elemental components. The study done in this project is basically for M20 grade concrete subjected to various temperature and thus the changes in properties are marked and highlighted. This project aims to show the behavior of concrete at various temperature and changes in its compressive strength and physical properties. Results show mark able behaviors of concrete which make it further more topic of interest. Results show mark able behavior of concrete which makes it furthers more topic of interest. The study reveals that concrete has very distinct bonding properties that change with change in exposure conditions.
