The invention discloses a rapid-hardening high-belite calcium sulfoaluminate cement clinker and relates generally to a rapid-hardening high-belite calcium sulfoaluminate cement clinker and methods to use and to manufacture the clinker. The clinker of the present invention comprises 20% to 35% by weight of C.sub.4A.sub.3S 3% to 9% by weight of C.sub.4AF, 37% to 47% by weight of C.sub.2S, 0.5% to 4.6% by weight of f-Ca and 14% to 26.3% by weight of CaSO.sub.4. The chemical compositions of the clinker are 12.9% to 16.1% by weight of SiO.sub.2, 12% to 19% by weight of Al.sub.2O.sub.3, 1% to 3% by weight of Fe.sub.2O.sub.3, 49% to 54% by weight of CaO and 12% to 18.43% by weight of SO.sub.3. It is manufactured by calcining, at a temperature of 1300 C.50 C. in a rotary kiln, the raw meal, comprising 33% to 62% by weight of limestone, 10.5% to 28% by weight of fly ash, and 19% to 45% by weight of FGD gypsum. A group of rapid-hardening high-strength cements of various strength classes can be manufactured by mixing and grinding 26% to 97% by weight of clinker, 3% to 19% by weight of anhydrite and 0% to 55% by weight of granulated blast furnace slag.

The invention comprises a method of making lime, dolomitic lime, hydraulic cement such as portland cement clinker and co-products such as pozzolan, acids, alumina, silica and the like. The method comprises providing 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 chemical composition and reacting the hyaloclastite with a first hydrochloric acid to create a first salt, precipitating the calcium ions to react with OH.sup. to form calcium hydroxide and heating the calcium hydroxide to create calcium oxide, alite and belite.

Provided herein are compositions, methods, and systems related to bimodal, trimodal, and/or multi-modal distribution of reactive vaterite cement particles.
