Annotation:
The article presents the results of study of the influence of high temperatures caused by the fire over the changes in bending strength of steel fiber reinforced concrete with high strength cement-sand matrix under various percent of reinforcement by fiber of various geometry and strength characteristics. It is demonstrated that within the temperature range from 20 to 1100 °C the tensile bending strength value depends on the all characteristics of fiber.
