A test program was conducted to define the variations in mechanical properties of a limestone aggregate concrete and a lightweight insulating concrete exposed to elevated temperatures. Four test series were conducted: (1) unconfined compression; (2) shear; (3) rebar bond; and (4) sustained loading. This thesis reports a study of some of the mechanical properties of steel fiber reinforced concrete (SFRC) after being subjected to different elevated heating temperatures, ranging between ℃ and ℃, in relation to non-reinforced concrete properties.   A total of concrete specimens are tested to study the effect of including hooked-end steel fiber reinforcement on the mechanical properties of high-strength fiber reinforced concrete. Fiber content ranges from zero to percent by volume, and the concrete matrix compressive strength is about MPa (13, psi). Mechanical properties of concrete were studied at different high temperatures, including compressive strength, splitting tensile strength, modulus of elasticity, and ultimate strain. Test results showed a reduction in the studied properties by different rates for different additives, and for each temperature, the decrease was very limited at a Author: Zine El Abidine Rahmouni, Nadia Tebbal.
