Thermodynamic equilibrium calculations in cementitious systems (2010, background): “Super sulfated slag cements exhibit, similar to slags blended with Portland cement, somewhat lower pH values than Portland cements [139, 140], while alkali activated slag systems are characterized by their high pH values [141–143].”
A physico-chemical basis for novel cementitious binders (2011, background): “The main hydration products are ettringite and C–S– H, with lesser amounts of hydrotalcite [59,60].”
Hydration of a low-alkali CEM III/B–SiO2 cement (LAC) (2012, background): “In alkali activated or supersulfated slags even more strongly reducing conditions have been observed as indicated by the higher sulfide/sulfate ratio in the pore solution [43,63,80,83].”
Advances in alternative cementitious binders (2011, methodology): “The composition of the pore solution is dominated by sulfate, calcium and alkali ions at early ages (b1 day) [132,133].”
