In this study, the compressive behavior of 55% HVFA(High Volume Fly Ash) concrete was performed by experiment with 6 RC columns. From the test results, it was shown that yield load of tied steel, yield load of longitudinal steel and ultimate loads are produced sequently. And there was no differences between ordinay concrete and HVFA concrete.
