Abstract: This research includes preparation (NR50/SBR50/Oyster Shell Powder OSP) composites while the loading ratio of OSP were 0, 5, 10, 15, 20, 25, 30, 40, 60, 80, 100 pphr. The examination of FTIR (Fourier Transform Infrared analysis) of some specimen composites were carried out and study the effect of calcium carbonate (Oyster Shell Powder OSP) grain size <225 μ on the rheological properties of (NR50/SBR50/OSP) composites with different loading ratio of (OSP). The device used to examine the characteristics is oscillating disc rheometer according ASTM D-2705 and temperature 185°C, pressure 10 bar and time 6 min. These rheological properties included the scorch time (ts2), cure time (tc90), viscosity, Maximum torque (MH), Minimum torque (ML) while the results of all these properties were decreasing with increase the loading ratio of OSP with or without C.B 10 pphr also all these properties were decreasing after addition C.B = 10 pphr for the same loading ratio of OSP except maximum and minimum torque at high loading ratio.
