The steel fibre reinforced concrete in structures provides good mechanical and physical characteristics and such material applications are increasing. At the same time, if structure is subjected to thermal load it is affecting both properties of reinforcement and matrix as well. The aim of the present research is to investigate the degradation of the characteristics of fibres, randomly distributed in the body of concrete block. A short steel fibre reinforced concrete slabs (400x300x18 cm) [1], [2] with homogeneously distributed fibres was undergone to calefaction process from one side (dimension of 16.5x14.5x15 cm). Fibre fracture process was performed based on the single fibre pull-out test by preparing the specimens with fibre from calefacted SFRC block. Experimental curves from each layer were compared with different layer of fibres and investigation had shown that higher load-bearing capacity is there over the thermal loaded fibre. The conclusion were made with the microscopic results and the experimental data.
