The objective of this study is to evaluate the feasibility of replacing limestone fines by biomass ash "wood ash" in the production of a self-compacting concrete (SCC). The ash is used at percentages ranging from 0%, 3% and 15% to partially replace limestone fines according to the formulation of Shen (LGC). Experimental studies, such as compressive strength and flexural tensile strength, are conducted to determine the mechanical properties of self-compacting concrete in the hardened state. The workability and fresh density of the mix were also studied. The results show that the use of biomass ash in self-compacting concrete gives performances as comparable to the reference SCC
