ABSTRACT
In this paper, the results of 6 steel fibre reinforced reactive powder concrete columns with 150 mm square cross sections are reported. The columns were tested to failure under load at various loading eccentricities. The reactive powder concrete mix contained 2% (by volume) of 0.2 mm diameter by 13 mm long straight steel fibres with a concrete strength of 150 Mpa. The columns contained either four or seven percent of longitudinal reinforcement but no tie reinforcement in the test region. Experimental data on strength, lateral and axial deformations and failure mode was obtained for each test. All the columns failed in a controlled manner and no buckling of the longitudinal steel or cover spalling was observed, even well beyond the peak load.
