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 compositions and methods relative to controlling hydration onset of an alkaline earth metal oxide such as calcium oxide, comprising heating an inorganic alkaline earth metal oxide to sub-calcination temperatures in the presence of organic material comprising a carbohydrate, an amino-carboxylic acid, a hydroxycarboxylic acid, or a mixture thereof. Preferred treated particles comprise at least 40% and more preferably at least 80% by dry weight calcium oxide which is heated in the presence of ascorbic acid and a starch. Treated particles of the present invention manifest an unexpected, surprising hydration induction postponement behavior as demonstrated through calorimetric testing.
