Green cements, which can be carbon neutral or negative, can be prepared at lower temperatures (450° C.-500° C.) by utilizing feed compositions comprising (i) TiO2, TaOxNy, TiOxNy, RuO2, Pt, TaO, band gap materials, or a first mixture thereof; (ii) Al2O3; and (iii) Ca2SiO4, MgSiO2, MnSiO2, or a second mixture thereof; and spent wash with melanoidin as a binder. |
