EXPERIMENTAL INVESTIGATI ON THE PROPERTIES OF M30 GRADE OF CONCRETE USING STEEL FIBERS AND GGBS (GROUND GRANULATED BLAST FURNACE SLAG) 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 compressive strength test on (150mmx150mmx150mm) size cubes and split tensile strength test on (300mmx150mm) size cylinder. Finally, the strength performance of slag blended fiber reinforced concrete is compared with the performance of conventional concrete
