External Sulphate Attack on Alkali-Activated Slag and Slag/Fly Ash Concrete [PDF]
Buildings, 2022 Two types of alkali-activated material (AAM) concretes were exposed to various sulphate bearing-solutions for over two years. Physical changes to the concrete specimen and chemical changes in the exposure liquid were studied in an attempt to understand how sulphate attack occurs in such binders and the role the mix variables play in offering resistance

Mechanism of Alkali‐Activated Copper‐Nickel Slag Material [PDF]
Advances in Civil Engineering, 2020 A copper‐nickel slag‐based alkali‐activated cementing material (CNSCM) for backfilling was prepared using copper‐nickel slag as a raw material and sodium silicate (SS) as an activating agent. The effects of SS content (6%, 8%, and 10%) and curing humidity on the compressive strength of CNSCM were investigated using an electronic universal testing ...
