EXPERIMENTAL AND ECONOMICAL ANALYSIS OF CONCRETE USING STEEL FIBER AND GGBS AS PARTIAL REPLACEMENT OF CEMENT

This experimental investigation is carried out to study the different strength characteristics of concrete with partial replacement of cement with ground granulated blast furnace slag (GGBS) and addition of steel fiber. In this investigation M30 grade of concrete is replaced with ground granulated blast furnace slag (15%, 25%, 35%, and 45%) by weight and addition of steel fiber having dimensions (0.45 x 25mm) in different percentage (1%, 1.5%, 2%, and 2.5%).Strength of concrete was determined by performing flexural strength (150mmx150mmx700mm) size beam. Economical and technical analysis of GGBS and steel fiber in concrete has been done. Finally, the strength performance of slag blended fiber reinforced concrete is compared with the performance of conventional concrete.
