Feng et al. [85] found that it was necessary to calcine albite at 1000 °C with NaOH or Na 2 CO 3 as activator in order to reach acceptable compressive strength (43-44 MPa at 28 days) in one-part geopolymer. Albite is often found in mine tailings [86], [87] and thus could represent a potential low-cost precursor.
