solid slurries such as ground calcium carbonate slurries the inclusion of a small amount of water structure breaker inhibits change in the solution structure over that of a typical slurry lacking the water structure breaker allowing longer storage and distribution periods for such slurries application_number US 201013145709 A description the stabilization of high solids slurries is carried out by the stabilization of the liquid aqueous phase structure traditionally the focus has been on the stabilization of the interface between the solid particle and the aqueous phase it has been discovered that by inclusion of an agent to inhibit changes in the aqueous solution 39 s structure the slurry is stable and does not undergo the adverse changes with aging that complicate the use of the slurries in an embodiment of the invention an aqueous suspension of ground calcium carbonate gcc is stabilized by the inclusion of a small amount of a dispersant and a small amount of a water structure breaker which stabilizes the structure of the aqueous phase as can be monitored by infrared spectroscopy for example in one embodiment of the invention the dispersant can be the sodium salt of polyacrylic acid and the water structure breaker can be ethylene glycol the inclusion of the water structure breaker has been found to stabilize gcc slurries against the common symptoms of aging particularly an increase in viscosity of the slurry in other embodiments.
