Effect of Steel Fiber Type on Compressive Strength and Modules of Rupture on Reactive Powder Concrete (RPC)

Ban Fadhil Salman

Abstract: In concrete technology reactive powder concrete (RPC) is the latest investigation and its very important because Concrete alone was very weak in tensile strength and its ductility very limited and few resistance to cracking. Different types of fiber reinforced concrete are now used with plain concrete to produce high flexural strength, good performance in tensile strength, and high modulus of rupture and few in cracking appeared. In the present may researches appears to study the properties of steel fiber in reinforced concrete like flexure strength, tensile strength and compressive strength. In this study use reactive powder concrete with two type of steel fiber (end hook and micro), and investigate compressive strength, modules of rapture and cracks appear by used cube (100*100*100) mm and prism (385*75*75) mm. And used steel fiber range of (0 and 1 %) from total volume of concrete. From test results steel fibers significant increase ductility and strength.
