(57) The invention comprises a method of making a hydraulic cement clinker. The method comprises delivering a natural calcium-iron-aluminosilicate mineral from one or more of hyaloclastite, lava, scoria, volcanic glass, volcanic ash, or any other mineral of a basaltic or intermediate basaltic chemical composition and blending it in ground form with limestone, calcium oxide or calcium hydroxide. The blended mixture is calcined in a portland cement clinker kiln at an elevated temperature and for a time sufficient to form a hydraulic cement clinker.
