Experimental research for the effect of high temperature on the mechanical properties of steel fiber-reinforced concrete

Tefaruk HAKTANIR | Fatih ALTUN

It is widely known that addition of steel fibers to concrete improves properties of concrete having brittle behavior. This affects the behavior in a positive way particularly by increasing ductility of the concrete. In this study, the results of the effect of high temperature on steel–fiber concrete were investigated. RC80/ 60 BN type steel–fibers were added to experimental concrete as in the rates of 0%, 0.5%, 1% and 1.5% by volume and concrete cylinder samples with 7, 28 and 90-day were tested. Produced cylinder samples were exposed to 900 °C, 1000 °C, 1100 °C and 1200 °C temperatures in the ...Daha fazlası
