Properties of Sawdust Concrete DOI:  https://doi.org/10.30564/jbms.v4i2.4818 Abstract This work examined the structural properties of concrete obtained bypartially replacing cement with sawdust ash. The sawdust ash which is apozzolan was obtained by burning sawdust which is a waste product fromprocessing of timber in an open air. The burnt ash was passed through a150 µm metric sieve to obtain the ash used. Physical and chemical analysiswere performed on the ash to verify its suitability as a partial substitute forcement in concrete. Chemical analysis was also carried out on the OrdinaryPortland Cement (OPC) sample. Concrete mixes were produced by replacing OPC with 0%, 5%, 10%, 20% and 30% of Sawdust Ash (SDA). Bothfresh and hardened properties of the concrete produced were investigated.The chemical investigation on the ash showed that it contained most ofthe basic compounds found in OPC making it suitable to serve as a partialsubstitute for OPC in concrete. Investigation on the co...
