Abstract
The need of high strength concrete (H. S. C.) is increasing in the recent years. This material becomes necessary, but it is brittle .So, metallic fibers are used to enhance composite properties of (H. S. C.).The enhanced properties include tensile strength, compressive strength, elastic modulus, crack resistance, crack control, durability, fatigue life, resistance to impact and abrasion, shrinkage, expansion, thermal characteristics, and fire resistance of concrete .There is little information in the available literature about the bond characteristics for the different forms of rib geometry of the deformed bars on the strength between steel and high-strength fiber-reinforced concrete for different relative rib areas and fibers types . The main objective of this research is to study the effect of using Metallic and Non Metallic- Fiber and rib geometry of steel bars on bond strength for high strength concrete (H. S. C.). Also Pattern of cracks, final mode of failure and deformational characteristics (direct slip for pull-out) were investigated.
