Enhancing Freeze-Thaw Resistance of Alkali-Activated Slag by Metakaolin. [PDF]
ACS Omega, 2023 Incorporating metakaolin (MK) into slag to prepare alkali-activated materials can reduce shrinkage and improve the durability of alkali-activated slag (AAS). But its durability under freeze–thaw conditions is unknown.

Alkali-Activated Slag Coatings for Fire Protection of OPC Concrete. [PDF]
Materials (Basel), 2023 During a fire, ordinary Portland cement (OPC) systems lose their mechanical properties. For this reason, it is important to find a way to protect it. This study suggested alternative uses of slag and phosphogypsum to produce coatings for fire-resistant applications. Five compositions of 10 mm thick alkali-activated slag coatings were investigated.
