The minerals powders are much applied on polymeric materials to better its properties and to promote new applications. The rice husk ash powder - RHS is a mineral compound has been applied on polymeric compounds to increase the stiffness. This work presents studies of different sizes of particles of RHS applied at different concentrations in polypropylene. To study the mechanical properties were applied techniques of Charpy Impact Resistance and Uniaxial Tensile Analysis. The morphology was observed using the optical microscope. The results showed that the CCA may be an alternative in the incorporation of mineral loads in polypropylene, since this is a waste product generated in the production of rice, thus the complete closure of the production cycle of the cereal.
