Abstract
Reactive Powder Concrete (RPC), which is an Ultra High Performance Concrete (UHPC), represents one of the most recent technological developments of the construction industry. This research is devoted to evaluate and analyze the effect of using different cement and silica fume contents as well as using a new type of steel fibers on the behaviour of the reinforced reactive concrete cast by using materials from North Sinai. The experimental program was planned to study the behaviour of the reactive powder concrete under the previous parameters in compressive strength, modulus of elasticity, indirect tensile strength and the flexural strength of the prepared specimens. A study also for the load deflection behaviour of beams cast using this type of reactive concrete was executed experimentally and analytically using a nonlinear computer program based on finite element technique. A comparison between analytical and experimental results was carried out to evaluate the efficiency and the accuracy of the used nonlinear computer program. A compressive strength of 1545 kg/cm2, indirect tensile strength of 119.8 kg/cm2, modulus of elasticity of 451000 kg/cm2 and flexural strength of 302.6 kg/cm2 were reached. The computer program results were practically close enough to the experimental results. The numerical analysis with the chosen finite element technique presented a good simulation to the reactive concrete.
