Abstract: The natural pozzolans studied are commercial products and come from the volcanic islands of Milos and Kimolos as well as North Greece mainland. The materials were characterised mineralogically and chemically by XRD and SEM/EDX respectively, while their reactivity with calcium hydroxide was studied through a pozzolanic activity test. In addition, five different lime-pozzolan mixtures were prepared and studied for their compressive strength at four preset curing periods (one, three, six and twelve months). The results indicated that having the pozzolans similar chemical and mineralogical composition, the main parameter that affected their reactivity and the strength of the produced mixtures was the grain size distribution of the pozzolans within the range of 0-63µm.
