Abstract

This article displays the aftereffects of a test examination on the mechanical behavior of Self Compacting Concrete (SCC) strengthened with Ground Granulated Blast Furnace Slag (GGBS) and 1.0% hybrid fibers (micro steel fiber, brass coated steel fiber& glass fiber) by the weight of cement. The hybrid fibre taken as micro steel fibre- glass fibre and brass coated steel fibre- glass fibre in the proportion of 1/0, 0.75/0.25, 0.50/0.50, 0.25/0.75, 0/1 from the whole. In this present investigation fresh properties, compressive strength, split tensile strength and flexural strength were accomplished for different fibre proportions. The results promising that inclusion of fibers, especially for steel -glass fibre and brass coated steel- glass fibers combination improved the mechanical properties of concrete. It was seen from the test results there was a decrease in usefulness with an expansion in ?ber content. It was discovered that glass ?bers didn't bestow e?ect on concrete than others. The strength examines show that incorporation of higher percentage glass fibre

reinforcement of steel in the concretes [3,4].On the other hand, lot of international standards and guiding principle for idea about FRC restricted their use in structural applications. The reality of those past researches is that it only explores crack controls and durability improvements [5]. The Effect of Reinforcement on Steel Fibers, there has been a lot of design guidelines and principles as partial replacement has increased tremendously in the last two decades. New fib Model-Coden and the standard principles are used as a worldwide indication imperceptibly decreases the strength than steel and brass coated steel fibre but it is also contributes higher strength equated to conventional. 

Keywords- Hybrid fibre, Self compacting concretes, Mechanical properties.
