Abstract
An aqueous composition comprising cement and a mixed metal layered hydroxide which demonstrates thixotropic properties. The mixed metal layered hydroxide is essentially monolayer. An example of such a layered hydroxide useful in this composition is magnesium aluminum hydroxychloride. These cement compositions are thixotropic and shear thinning, harden without settling and do not dewater upon standing.
