In this study, the influence of the heating process on fracture mechanics parameters of concrete has been investigated experimentally. As the first step for the heating test, the influence of material contents in concrete on fracture mechanics parameter was investigated at room temperature. Then heating tests that changed the maximum temperature and the cooling method were carried out. Consequently, a strong correlation between the fracture mechanics parameter and the sand percentage was indicated. After the heating, the strength of concrete decreased. The water-cooling after heating damaged the surface of specimen and influenced on the maximum load of P-CMOD curve and the tension softening curve.
