ABSTRACT:
A smectite clay is provided as an elevated solids aqueous slurry e.g. up to 50% solids, which is composed of the smectite clay slurried or dispersed in water containing an effective concentration of a monovalent salt. When such a salt is present in the clay slurry, the clay does not swell appreciably, is essentially inactive, and the slurry can be shipped and stored without creating a gelling problem. When this slurry is diluted with fresh water at the point of application to make it of the desired solids content for use, the smectite clay is activated and exhibits the desired properties, such as viscosity, retention, etc.
