Scale-inhibiting cocrystals for treatment of a subterranean formation
The present invention relates to cocrystals including a scale-inhibiting compound, and methods of using the cocrystals for treating a subterranean formation. In various embodiments, the present invention provides a method of treating a subterranean formation including obtaining or providing a composition including cocrystals. Each cocrystal independently includes a scale-inhibiting compound and a secondary material. The method also includes placing the composition in a subterranean formation.

EARLY STRENGTH ENHANCING CONCRETE ADMIXTURE
The present invention provides an admixture composition comprising a liquid suspension of colloidal silica, siloxane, and polycarboxylate polymer cement dispersant for enhancing early age strength, finishability, and other properties in hydratable cementitious compositions such as concrete (e.g., shotcrete). An inventive method involves mixing the components together in a specific sequence, thereby to obtain a stable liquid suspension. This attainment of a stable liquid suspension is surprising and unexpected because (i) the polycarboxylate polymer cement dispersant and siloxane components are incompatible and immiscible with one another; and (ii) that colloidal silica and siloxane compound are incompatible and immiscible with one another. Yet, the present inventors achieved an additive in the form of a stable liquid suspension which can be conveniently dosed into concretes and shotcrete mixtures, to enhance early age strength, and to improve workability and rheology in terms of finishability of concrete surfaces and improved rebound performance in shotcrete applications.
