%X This study examines some physical and mechanical characteristics of polypropylene (PP) and calcium trioxocarbonate IV (CaCO<sub>3</sub>) composites prepared by melt blending. The mechanical (tensile strength and impact energy resistance) and physical (density and water absorption capacity) properties of the composites were evaluated using 0% - 40% of the filler. The results showed that 20%-CaCO<sub>3</sub> addition improved the ultimate tensile stress by 58%, and the UTS is 84% better when 25%-CaCO<sub>3</sub> addition is made while the impact resistance decline by 8 and 12% respectively at these two compositions. In addition, the density only differ from that of pure PP at 25% CaCO<sub>3</sub> addition by 18% increment, however, water absorption increased by 400% at 10%-CaCO<sub>3</sub> addition.
