This study explores the lime-pozzolana pastes made from high calcium hydrated lime blended with type F fly ash and silica fume, with the total pozzolana content up to 40%. Research focuses on the development of the compressive strength by varying the water-binder ratio, powder proportioning, fineness of lime, and curing conditions. The lime-pozzolana cement shows good promise as a binder which can be used Alongside the Portland cement. With lower unit weight and higher compressive strength per unit weight than the Portland cement paste, the lime-pozzolana pastes can reduce the weight of structural elements and the overall cost of structures.
