Effect of Steel Fibers on the Mechanical Strength of Concrete

The study is based on designing the mix design of concrete for class named MR_DK_E1: C30/37, one most widely used classes normal concrete. To see effect fibers concrete, we will three mixtures that in other components are similar to first mixture "Normal Concrete",but as an additive, add 0.75%, 1.5%, and 2.0% steel fiber (Romfracht SRL Company Profile) mass Although some researchers have already detailed favourable qualities reinforced (SFRC), there very little data regarding performance this type get know something more terms properties during realization work perform experimental tests European standards understand closely how affect growth improvement with lime aggregate local cement CEM II/BM (WL) 42.5N, applying different percentages volume For all mixtures, necessary wet hardened be performed, while obtained results compared between same kinds, where conclusions recommendations drawn can serve further studies use engineering practice our country. Three fibre content were applied. Experiments show selected content, a ductile behaviour higher load levels post-cracking range obtained. forms basis selection suitable types their efficient combination regular bar reinforcement. Also, special attention given SFRC constructive elements. This research concerning has been performed building materials laboratory near UBT, Proing laboratory-Pristina, GIM-Skopje (Kosovo).
