The Structural Behavior of Fiber Reinforced Self_compacted concrete

The study is concerned with the structural behavior of (12) reinforced T-shaped cross-section beams made of self-compacting concrete under flexural with two types of fibers (polypropylene and steel fibers). Compression and tensile strengths, deflection, ductility and cracking behavior are considered. Experimental results are compared with these evaluated based on the (ACI 318 – 08). The variables studied are reinforcing ratio (%ρ) (between %4.4907 - %6.0434) using different sizes of reinforcing steel bars (Ф25mm, Ф20mm, Ф16mm, Ф12mm, Ф6mm, Ф4mm, and Ф6mm wire mesh), in addition to two fibers, [polypropylene (RHEO-FIBERS®)and steel fibers (FIBERFORCE®) at a rate of [(1kg/m3) & (0.5%)], respectively.
