Abstract


Now a day concrete is being used extensively in the construction that might be subjected to elevated temperatures. The behavior of concrete structures at elevated temperatures is significant importance in predicting the safety of structures in response to certain accidents or particular service conditions. This paper deals with the mechanical properties of concrete with steel fibers subjected to temperatures up to 500°C. The specimens were kept in oven for 1 hour. Different materials were used in the concrete mixes of M 50 have been designed along with crimped steel fibers from 0.5 to 4% by weight of ordinary Portland cement and river sand was used. Specimens were made and subjected to room temperature, 100, 200, 300, 400 and 500°C. In this study, the statically related (model) between compressive and tensile strength value is introduced. Regression analysis is used to obtain this type of relation. This investigation developed some important data on the properties of concrete exposed to elevated temperatures up to 500°C.
