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.
