Abstract: An experimental program was carried out to design and study the properties of self-compacting concrete (SCC) made with coal bottom ash. The mixes were prepared with coal bottom ash as partial replacement of fine aggregates. Tests were conducted for slump flow, J-ring, V-funnel, L-box and U-box, compressive strength, splitting tensile strength, deicing salt surface scaling, carbonation and rapid chloride penetration resistance Results indicated that SCC mixes achieved 28-day compressive strength between 25.8 and 35.2 MPa and splitting tensile strength between 1.9 and 2.4 MPa. Compressive and split tensile strength increased with the increase in age. Carbonation depth and deicing salt surface scaling weight loss increased with the increase in bottom ash. Maximum carbonation depth was observed to be 1.17mm at 90 days and 1.66 mm at 365 days for SCC with 30% bottom ash content. SCC mixes made with bottom ash exhibited very low chloride permeability resistance (between 381 and 800 Coulomb).
