Abstract: The present invention provides a method and admixture composition for making hydratable cementitious compositions, ones believed to have much less stickiness in comparison to prior methods. Decreased stickiness in concrete mixes means that they are easier to pour or to cast into place, as well as easier to finish. Dispersant carboxylate polymers of the invention having this ability are characterized by possessing two different, relatively short chain lengths of polyalkyleneoxide units and low weight-average molecular weights.

Abstract: The present invention relates to modification of hydratable cement and cementitious materials, such as mortar cement and masonry or ready-mix concrete using ketone alcohol oil waste (“KAOW”) material, obtained as an alkali-soluble liquor waste byproduct at a certain stage in the commercial production of cyclohexanol and cyclohexanone. Preferred applications for KAOW are in chemical admixture formulations whereby KAOW is used to substitute for a portion of a cement dispersant such as sodium lignosulfonate, sodium gluconate, or other conventional dispersant. Another preferred use is in mortar cement and masonry concrete units such as blocks, pavers, curbstones, and other concrete masonry units wherein air void systems advantageously foster freeze-thaw durability.

Abstract: The present invention provides a method for treating clay-bearing aggregates, particularly those used for construction purposes, which involve introducing to clay-bearing aggregates an ion-exchanged polycondensate of dialkylamine and epichlorohydrin having anionic groups comprising both acetate and chloride ionic groups, wherein the acetate is present in an amount of 51-99 percent, and more preferably in the amount of 60-95 percent, based on molar concentration of the anionic groups, whereby chloride ionic groups are minimally present.
