Özet

When materials are faced with high temperature, physical and chemical changes in their structure and these changes are irreversible. It is crucial to predict these structure changes for buildings. In the study compressive strengths of concrete samples produced with mixing air carried additives for 5 different temperatures were tried to predict using multi linear regression and fuzzy logic methods. These samples were casted in of 50x100 mm dimension. The compressive strengths and ultrasound transition values were obtained on these samples. The higher temperature and ultrasound transition speeds were used as input for the determination of compressive strength values. As the result of the study, it was observed that the fuzzy logic model for the due to higher temperature and ultra sound transition values was better than the multi-linear regression model.
