摘要： The present invention is directed to a gypsum board and a method of making such gypsum board. For instance, the gypsum board comprises a gypsum core, a first facing material, and a second facing material wherein the first facing material and the second facing material sandwich the gypsum core. The gypsum core comprises a first gypsum core section and a second gypsum core section each comprising gypsum, wherein the first gypsum core section comprises a polyol compound and has a density higher than a density of the second gypsum core section.

摘要： Disclosed herein is a method of servicing a wellbore penetrating a subterranean formation with a thixotropic cement composition. The thixotropic cement composition comprises a cementitious material, maltodextrin, and an aqueous fluid, has a 10-minute gel strength of from about 30 lbf/100 ft2 to about 300 lbf/100 ft2, and can be used to reduce lost circulation in the wellbore. By incorporating maltodextrin into the thixotropic cement composition as disclosed herein, the thixotropic cement composition can have a similar 10-minute gel strength and an increased thickening time when compared to a reference composition.

摘要： A combination of retarders and regulators for hydration reaction of cementitious binders including clinkers based on Ye'elimite. Set retarders are calcium complexing agents, consisting of sugar acids, sugars, sugar alcohols, hydroxycarboxylic acids, phosphates, phosphonates, borates and amines. Regulator general formula (I) is where M is H, NH4 or chosen from monovalent or divalent metal of groups Ia, IIa, IIIa, Ib, IIb, IVb, VIb, VIIb or VIIIb of periodic table of elements, where M is a divalent metal, a second equivalent of R—SO3 is present, and M is chosen from group consisting of H, NH4, Li, Na, K, MgX, CaX, or NiX with X═RSO3, and R is chosen from H, NH2, OH or from hydrocarbon chain with 1-18 C atoms which may be substituted by N and/or O and/or which may be linear or branched and/or which contain one or more unsaturated bonds and/or cycloaliphatic and/or aromatic moieties.
