A process for producing a cement binder composition including one or more magnesium carbonates having the general formula w MgCO3. x MgO. y Mg(OH)2 . z H2O in which w is a number equal to or greater than 1, at least one of x, y and z is a number greater than 0 and w, x, y and z may be (but need not be) integers is described. The process is characterised by (a) heating magnesite to liberate carbon dioxide gas and produce a solid product including magnesium oxide and (b) contacting an aqueous mixture including the magnesium oxide produced in step (a) with a source of carbonate ions at a temperature in the range 25 to 120° C. to produce at least one of the magnesium carbonates.
