Low pressure steam-curing hydration of mixtures with different fly-ash-to-lime ratios compacted at 50 and 150 MPA was studied. The pastes were cured for between 8 and 72 h at 60 ยฐ , 75 ยฐ and 90oc. For comparative purposes duplicate samples were treated for 28 days at 25oc. Compressive strength tests
