AB The main objective of this work is to study the hydration and properties of calciumsulfoaluminate cement pastesblended with fly ash (FA) and the corresponding mortars at different hydration ages. Laboratory X-ray powderdiffraction, rheological studies, thermal analysis, porosimetry and compressive strength measurements wereperformed. The analysis of the diffraction data by Rietveld method allowed quantifying crystalline phases andoverall amorphous contents. The studied parameters were: i) FA content, 0, 15 and 30 wt.%; and ii) water addition,water-to-CSA mass ratio (w/CSA = 0.50 and 0.65), and water-to-binder mass ratio (w/b = 0.50). Finally,compressive strengths after 6 months of 0 and 15 wt.% FA [w/CSA = 0.50] mortars were similar: 73 ± 2 and72 ± 3 MPa, respectively. This is justified by the filler effect of the FA as no strong evidences of reactivity of FAwith CSA were observed. These results support the partial substitution of CSA cements with FA with the economicand environmental benefits
