This paper presents the result of a study on the use of sawdust waste incineration fly ash (SWIFA) as supplementary cementing materials. Tests on the setting times and strength development of cement paste and mortar with up to 30 percent SWIFA were carried out. Results of the setting times and compressive strengths show that with increasing amounts of SWIFA, the setting times of the paste were extended and the compressive strengths decreased. Pozzolanic activity index of the material was also confirmed to be approximately 76 percent and that the material performed better in a nitric acid solution environment than in sulphuric acid solution.
