摘要： A hydraulic well cementing composition is disclosed. The well cementing composition contains a hydraulic cement and a fluid loss additive. The fluid loss additive is the polymerization reaction product of a two vinylamide monomers, wherein the polymerization reaction is conducted in the presence of a molecular weight control agent. One of the vinylamide monomers includes a sulfonic acid function, the second vinylamide monomer does not include a sulfonic acid function. The fluid loss additive controls fluid loss at temperatures up to 350° F.

摘要： The present invention provides compositions and methods involving the use of a carboxylate graft polymer having high molecular weight and low ratio of acid-to-polyoxyalkylene groups. Such clay-mitigation is particularly useful for treating clay and clay-bearing aggregates, particularly those aggregates used for construction purposes. The present invention minimizes the need to wash the aggregates, thus preserving fine aggregates (“fines”) content in construction materials, and thereby beneficiating the performance and/or properties of construction materials containing the clay-bearing aggregates.

摘要： The present invention relates to cationic copolymers, a process for the production of these cationic copolymers and the use of these cationic copolymers as dispersants for geopolymer binder systems. These cationic copolymers where the cationic charge is due to the presence of certain cyclic and/or polycationic groups are stable towards Hoffmann elimination that would otherwise occur at very high pH values. Moreover, the dispersing effect of cationic polymers can be further enhanced through the addition of polyvalent anions.

摘要： The present invention provides a composition and method for modifying a hydratable cementitious composition such as concrete or mortar using at least three different, distinct carboxylate polymers, even when clay is present in the concrete or mortar that would otherwise diminish dosage efficiency of polycarboxylate polymer used as dispersant. The three polycarboxylate polymers, designated as Polymer I, Polymer II, and Polymer II, are derived from monomer Components A, B, and C wherein Component A is an unsaturated carboxylic acid, Component B is a polyoxyalkylene, and Component C is an unsaturated carboxylate ester. The component molar ratio ranges for A:B:C are different as between Polymers I and II; while a distinct component molar ratio A:B+C is identified for Polymer III. When treated with these three different polycarboxylate polymers, the hydratable cementitious composition is surprisingly enhanced in terms of initial workability and slump retention, especially if clay is present.
