Mechanical properties of steel fiber-reinforced rubber concrete after elevated temperature.

ABSTRACT: The frequency of engineering fires is increasing, and the study of the residual mechanical properties of steel fiber-reinforced rubber concrete (SFRRC) after high temperatures is essential for evaluating its load-bearing capacity after fire. This study examines the mechanical properties of SFRRC after being subjected to elevated temperatures, considering the impacts of varying steel fiber amounts (V_sf =0.6, 1.2%) and different rubber substitution ratio (r_g=0, 5, 10, 15%) on the specimens after different temperatures (20, 200, 400, 600, 800 °C). All specimens were tested in cubic and axial compression, split tensile and four-point flexure tests. The findings indicated that steel fibers and rubber enhance the durability and safety of concrete by reducing the risk of cra
