Abstract

This research aims to investigate and evaluate an ultra high strength concrete (UHSC) cast using economical materials. Reactive powder concrete (RPC), as a one of UHSC types were studied. Its mechanical properties were investigated and evaluated by studying the effects of using different cement and silica fume contents and new steel fibers' aspect ratios as reinforcement for this concrete. A compressive strength of about 154MPa, indirect tensile strength of 12MPa, modulus of elasticity of 45GPa and flexural strength of 30MPa have been achieved for reinforced RPC contains 800 kg/m3 cement content and silica fume content 30% of cement weight. The test results showed adiquate improvements by increasing cement and silica fume contents as well as adding steel fibers on the compressive strength, modulus of elasticity and indirect tensile strength. It showed also a great positive effect on the flexural strength.
