Abstract

This paper describes about the experimental investigation for polypropylene fiber with waste steel slag aggregate Concrete-Filled Steel Tubular (CFST) column sections subjected to axial load. This study is aimed to investigate the effect of fiber reinforced steel slag aggregate concrete in composite section. Optimum replacement of Steel slag is identified with the compressive strength, split tensile strength and modulus of rupture experiment, in which 40% replacement of steel slag against course aggregate displayed better result, moreover the same volume is used in the CFST. During investigation columns were subjected to axial load, lateral and the axial deflection were measured. Experimental results show that the CFST column takes more loads, ductile and the presence of fiber increases the lateral deflection rather than the conventional column. Generally due to slenderness effect, column fails under buckling.
