The mechanical properties of locally cast RPC were investigated and evaluated by studying the effects of using different cement and silica fume contents and new steel fi bers’ aspect ratios as reinforce-ment for RPC. Specimens’ preparation, curing regimes and testing procedures to evaluate the com-pressive strength, the modulus of elasticity, the indirect tensile strength and the fl exural strength were discussed. A compressive strength of 154.5 MPa, indirect tensile strength of 11.98 MPa, mod-ulus of elasticity of 45.1 GPa and fl exural strength of 30.26 MPa have been achieved for reinforced RPC contains 800 kg/m³ cement content and silica fume content 30% of cement weight. The test results showed some improvements by increasing cement and silica fume contentsas well as adding steel fi bers on the compressive strength, modulus of elasticity and indirect tensile strength.}, type={Artykuły / Articles}, title={Economical Reactive Powder Concrete Cast Using Available Materials in North Sinai, Egypt}, URL={http://www.journals.pan.pl/Content/83868/mainfile.pdf}, keywords={Reactive Powder Concrete, Mechanical Properties, Cement Content, Silica Fume Content, Steel Fibers}, }
