Biomass has been used as agriculture, forest and energy resources. The combustion of biomass matter becomes biomass ash that is dumped without control or disposed in landfills. Thus, the recycling or treatment of biomass ash is required. Wood ash is one of largest portion of biomass ash. Therefore, the recycling of wood ash in construction area will provide both new types of renewable energy sources and an environmental solution reducing the waste. The main objective of this study is to explore the physical, mechanical properties of Ottawa 20/30 sand, wood ash and mixture of them including Scanning Electron Microscope (SEM), hydraulic conductivity, and consolidation. It was observed that, small addition of wood ash to Ottawa 20/30 sand reduced the permeability significantly without increasing compressibility much.
