A hydraulic composition is prepared by mixing (A) an admixture aqueous solution containing a water-soluble salt which is a water-reducing agent or setting retarder, and a water-soluble cellulose ether with (B) a fresh concrete composition containing a hydraulic substance, an aggregate, and water at job site. The method is effective for preventing the admixture solution from thickening even though the water-soluble cellulose ether without glyoxal treatment is used.

A process for making a cement, the cement containing a naturally occurring silicate bound in an organic binder, and a metal oxide. An example process includes dissolving the organic binder at least in part, using an effective amount of a chemical activator. An example process also includes providing the silicate to react with other components of the cement. An example process also includes providing the silicate to participate in crystal growth. An example process also includes providing the silicate so that the cement is a structural load bearing cement.
