	%X High temperature is one of the most detrimental
effects that cause important changes in concrete’s mechanical,
physical, and thermo-physical properties. As a result of these
changes, especially high strength concrete (HSC), may exhibit
damages such as cracks and spallings. To overcome this problem,
incorporating polymer fibers such as polypropylene (PP) in concrete
is a very well-known method. In this study, using RRH, as a
sustainable material, instead of PP fiber in HSC to prevent spallings
and improve physical and thermo-physical properties were
investigated. Therefore, seven HSC mixtures with 0.25 water to
binder ratio were prepared incorporating silica fume and blast furnace
slag. PP and RRH were used at 0.2-0.5% and 0.5-3% by weight of
cement, respectively. All specimens were subjected to high
temperatures (20 (control), 300, 600 and 900˚C) with a heating rate
of 2.5˚C/min and after cooling, residual physical and thermo-physical
properties were determined.
