Alkali-activated Portland blast-furnace slag cement: Mechanical properties and hydration
HighlightsAlkali-activated Portland GBFS cement (80%) develop greater mechanical strength at early ages.Alkaline activation of blended cements developed a denser microstructure.Hybrid cements had slower heat release rates and lower total released.Compressive strength of hybrid cements increased with the Na2O content of the systems.
AbstractThe aim of this article was to study the kinetic, the mechanical development and the microstructure of an alkali-activated blended Portland cement produced from the mixture of a granulated blast furnace slag and Portland cement in proportion 80% and 20% respectively. The hybrid cement reported compressive strength 4.5 and 10.8 times higher than the reference (100% Portland cement) when is activated with NaOH and waterglass (sodium silicate+NaOH) respectively. Similarly, the heat of hydration was reduced and the material presented a fairly dense and compact microstructure. The main products observed were gel C-S-H, C-A-S-H and hydrated gehlenite.
