ABSTRACT: This research is
conducted to study the experimental behavior of composite steel-concrete
columns with basalt additives. Various percentages of basalt are added to the
concrete mixes to investigate its effect on the total axial compressive
capacity of the columns. Expected failure scenarios of the columns are:
concrete compressive failure, buckling of steel section, and de-bonding between
steel and concrete sections. A conventional limestone composite column was used
as base mix. The results of the study indicate a significant improvement in
structural behavior and strength of the columns by increasing the percentage of
basalt content.
