Abstract

The purpose of this study is to investigate the strength and sulphate attack resistance of roller compacted concrete with circulating fluidized bed combustion (CFBC) ash. All mixtures were designed according to ACI 211.3R. CFBC ash was used to replace fine aggregate with various dosages (5, 10 and 15%) by weight. During casting, cylinders were vibrated and compacted with the pressures of 25 g/cm2, 50g/cm2  and 75 g/cm2, respectively. Results showed that high roller compacted pressure is benefitial to improve the mechanical  peoperties  of  roller  compacted  concrete.  CFBC  ash  can  increase  compressive  strength, splitting tensile strength and sulphate attack resistance of hardened concrete. From the test results, it could be concluded that CFBC ash might be used in RCC between  5% and  10% as fine aggregate replacement.
