This experimental study is based on self-dynamic concrete (SDC) with low fines that has greater flowability, passing ability and segregation resistance compared to self compacting concrete (SCC). Cement was replaced with Class F fly ash with 20, 40, and 60% by weight with fixed water binder ratio. Fresh properties such as slump flow, V-funnel, and J-ring test were performed. The hardened properties such as compressive strength, splitting tensile strength and flexural strength were also tested. In addition to fresh and hardened properties, cost analysis was also performed to check the cost effectiveness of SDC with control mix. The results of fresh properties showed that incorporation of fly ash exhibited excellent workability and flowability in fresh state. The mechanical properties such as compressive strength, flexural strength and splitting tensile strength were lesser at 28 days but attained comparable strengths as the curing age increased to 90 days for the mixture containing 20% fly ash. The cost analysis of SDC shows that it can reduce 14 to 33% of the total cost compared control concrete for the compressive strength of 25 to 30 MPa. © 2017 ASCE.
