    摘要: A method of producing gypsum building board, in which there is added, to an aqueous gypsum slurry containing a water swellable clay, a basic water-soluble polymer having preferential affinity for clay. The slurry is allowed to set so as to form a board. The basic water-soluble polymer may be, for example, a polyvinyl alcohol or a polymer consisting essentially of carbon, nitrogen and hydrogen and having amine groups (which may be primary, secondary, tertiary or quaternary) in the polymer backbone and/or in side chains thereof.

    摘要: The present invention discloses compositions and methods wherein polycarboxylate comb polymers are used as grinding additives. The comb polymers contain a carbon-containing backbone and pendant groups wherein oxyalkylene pendant groups contain one or more ether linkage groups for providing robustness to the polymer for resisting degradation during grinding and hence sustaining workability and strength of hydratable cementitious materials, such as cements, pozzolans, limestone, and other cementitious materials.
