摘要： A fire proof compound is provided including MgSO4.7H2O) (Mg4Si6O15(OH)2.6H2O) CaO (s)+H2O (1)⇄Ca(OH)2 (ΔHr=−63.7 kJ/mol of CaO) (CaSO4.2H2O) H4 Mg2 Si3 O10). The compound can be added to a gypsum substrate of a wallboard to manufacture a fire proof wallboard. The compound can also be mixed with a paint to provide a fire proof paint. In certain composition, the compound can also exhibit an electromagnetic field blocking property. An existing wallboard manufacturing process line can be modified to accept the additional process of adding the compound to the gypsum substrate of the wallboard.

摘要： Well-cementing compositions for use in high-pressure, high-temperature (HPHT) wells are often densified, and contain weighting agents such as hematite, ilmenite, barite and hausmannite. The weighting agents are usually finely divided to help keep them suspended in the cement slurry. At high temperatures, finely divided weighting agents based on metal oxides react with the calcium-silicate-hydrate binder in set Portland, cement, leading to cement deterioration. Finely divided weighting agents based on metal sulfates are inert with respect to calcium silicate hydrate; consequently, set-cement stability is preserved.

摘要： A formulation for use as a lost circulation preventive material is a cement-forming aqueous fluid comprising water, at least one viscoelastic surfactant (VES), at least one monovalent or multivalent salt, at least one magnesium powder, and at least one retarder. The formulation is used in a method of drilling into a subterranean formation that includes introducing into a wellbore passing at least partially through the subterranean formation the cement-forming aqueous fluid, and further increasing the viscosity of the aqueous fluid by the action of the VES forming elongated micelles; where the at least one monovalent salt is present in an amount effective to pseudo-crosslink the elongated VES micelles to further increase the viscosity of the aqueous fluid. The formulation further forms a cement by reacting the at least one magnesium powder and the water which reaction is retarded by the retarder. The water may be saline water.

摘要： Cementitious compositions and methods for preparing and using the cementitious compositions to yield hardened concrete. The cementitious compositions yield hardened concrete having reduced or attenuated water vapor emission and lower internal relative humidity (IRH). Cementitious compositions are characterized by the property of rapid surface drying while maintaining good workability, particularly when using porous lightweight aggregates that absorb substantial amounts of water. Methods of decreasing water availability and increasing surface drying of concrete, including lightweight concrete, are provided. A water soluble ionic salt may be used to sequester water within the pores and capillaries of the cement paste and/or porous lightweight aggregate by modifying the colligative property of pore water. The salt may be added directly to concrete or the concrete mix water, or, alternatively, aggregates may be infused with a water-salt solution to provide treated porous aggregates having improved water saturation and water retention.
