Method of printing marks on an optical article

A method of treating fly ash to modify the set time and the induction profile for a slurry comprising cement and the fly ash. The method comprising mixing fly ash with an aqueous solution comprising the calcium carbonate, thereby modifying the set time and the induction profile of the slurry comprising cement and the fly ash. A method of treating fly ash to modify the induction profile of a slurry comprising cement and the fly ash. The method comprising contacting fly ash with a wet gas stream comprising water vapor and carbon dioxide in an amount sufficient to react with the fly ash so as to modify the induction profile of the slurry comprising cement and the fly ash. Cement compositions comprising water, hydraulic cement, and carbonated fly, and associated methods of use.
