This paper presents experimental obtained data regarding the properties of self compacted concrete (SCC) with fly ash content, such as workability, compressive strength evolution over time in comparison with the reference (concrete without fly ash or concrete with limestone filler content). In this way, were realized two series of mixes: SCC with CEM I 52.5R and SCC with CEM II/B-M (S-LL) 42.5N.

Research realized showed that the addition of 20-34% fly ash of total powder amount is beneficial for the consistency and resistance to segregation of concrete in fresh state.

SCC compressive strengths at early age were significantly diminished by fly ash addition, but these are increasing until 360 days.
