One-Part Alkali-Activated Materials: State of the Art and Perspectives

Abstract: Alkali-activated materials (AAM) are recognized as potential alternatives to ordinary Portland cement (OPC) to limit CO2 emissions and beneficiate several wastes into useful products. Compared with its counterparts involving the concentrated aqueous alkali solutions, the development of “just add water” one-part alkali-activated materials (OP-AAM) has drawn much attention, mainly attributed to their benefits in overcoming the hazardous, irritating, and corrosive nature of activator solutions. This study starts … Show more

“…Despite all the side effects, compared to other AAMs exhibiting σ c values of approx. 50 MPa, our best result, that is from SI60, is slightly lower than the average (28 MPa), but the strength decisively improves after calcination, becoming up to 40% higher than a typical AAM, and displaying a five-fold increase in hardness, confirming that the calcination stage is a step that cannot be dismissed from the synthesis route [44][45][46]. However, when comparing them to bioactive ceramics and glass ceramics, our material presents lower mechanical properties, but they are not far from the target of 150 MPa of the theoretical bulk combeite material [47] and the cortical bones [48].…”
