  1. % is the percentage with respect to the binder (GGBS or OPC) mass.
  2. In the acronyms of the mixture ID, NH represents NaOH-activated slag, NC represents NaOH+Na2CO3-activated slag, NSi represents NaOH+Na2SiO3-activated slag, OPC represents ordinary Portland cement, A represents equivalent Na2O dosage in activator, Cl represents chloride dosage, N represents the incorporation of sodium nitrite.
