Abstract
Methods and composition are provided for deriving cement and/or supplementary cementitious materials, such as pozzolans, from one or more non-limestone materials, such as one or more non-limestone rocks and/or minerals. The non-limestone materials, e.g., non-limestone rocks and/or minerals, are processed in a manner that a desired product, e.g., cement and/or supplementary cementitious material, is produced.
Claims27
A method for producing a clinker from a solid comprising calcium chloride comprising:
- (a) combining the solid comprising calcium chloride with a solid comprising silica to produce a solid composition comprising calcium chloride and silica, wherein the molar ratio of Ca:
- Si in the solid composition comprising calcium chloride and silica is 2.5 to 3.5;
- (b) dechlorinating the solid composition comprising calcium chloride and silica to produce a dechlorinated composition comprising Ca and having less than 10% w/w Cl;
- and
- (c) heating the dechlorinated composition in the presence of a flux to produce a clinker.
