Abstract

Cement compsn. is mfd. by: adding CaO and Al2O3 cpds. to a non-ferrous waste slag and/or fuel residues in a furnace or burner; increasing the pH to activate Al2O3 component of the mixt.; adding an SO4 ion source and water so that an ettringite compsn. is formed which forms high grade pozzolanic material; and allowing the mixt. to cure to a cement compsn. - Pref. the first mixt. contains at least 8% CaO and at least 3.5% Al2O3, the CaO:Al2O3 ratio pref. being 2:1.
