Since last one decade self-compacting concrete is gaining interest as niche research area in advancement in concrete technology. This research study aimed to determine the mix design for optimum rheological properties of self compacting concrete when using pulverized fly ash as the cement replacement material. A number of trial mixes were designed to determine the rheological properties using V -funnel and flow measurement tests. The mixes that did comply with the specified rheological properties are to be tested for strength and porosity, in order to assess their engineering properties and durability characteristic. Under the optimal superplasticizer identified in this study (7kg!m\ adding fly ash to the mix did not give much variation from the control mix (55Mpa for control mix, 51Mpa for fly ash mix at 56-days), but the result for fly ash show high potential to achieve higher strength at later age.
