摘要： Disclosed is an acid-modified flour and a method of making the acid-modified flour. The acid-modified flour is desirably prepared using a dry milling process. A starting flour is combined with a strong acid to form a mixture. The mixture is heated. A neutralizer is added to increase the pH of the mixture. If desired, the mixture can be dried and any agglomerates can be removed. The acid-modified flour can be used as a binder in a slurry for preparing one or more gypsum layers in a gypsum board.

摘要： The present invention provides dry mixes for skim coat mortars having improved pot life and workability while reducing cellulose ether dosage comprising a white cement, one or more fillers having a sieve average particle size of from 15 to 60 microns, from 0.25 to 0.5 wt. % of one or more gel-like crosslinked cellulose ethers containing polyether groups, preferably, a mixed cellulose ether having polyoxypropylene dioxyethylene ether crosslinks, and from 1 to 2.5 wt. % of one or more polymer redispersible powders (RDP). At least one gel-like crosslinked cellulose ether has a crossover point as measured by oscillation rheometry, at which storage modulus (G′) and loss modulus (G″) intersect and are identical, of 1.0ω or less. The present invention also provides methods of using the dry mixes.

摘要： This document relates to methods for preventing or inhibiting the formation of micro-cracks and fractures in the cement of an oil well using cement compositions that contain cross-linked polyrotaxane additives. The cement compositions containing the cross-linked polyrotaxane additives exhibit increased stiffness without suffering a decrease in compressive strength, as compared to the same cement without the cross-linked polyrotaxane additive.

摘要： High-strength flowable fill compositions are disclosed. The compositions include cement, aggregate (e.g. sand), water, coloring agent, polymer, and fibers. In an embodiment, the compositions include an accelerant, e.g., calcium chloride or sodium bicarbonate and/or an air entraining agent. In an embodiment, the compositions include a water-proofing agent to eliminate efflorescence. The compositions have a compressive strength of between 300 psi and 3000 psi after 1 day, a compressive strength of between 900 psi and 4000 psi after 7 days, and a compressive strength of between 1200 psi and 5000 psi after 28 days.

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.
