Modifying cementitious compositions using ketone alcohol oil waste

An additive composition for modifying a hydratable cementitious composition, comprising:

• (A) at least one cement dispersant for dispersing hydratable cementitious particles within an aqueous environment;
• (B) a ketone alcohol oil waste (“KAOW”) byproduct obtained from a commercial production process whereby cyclohexanol and cyclohexanone are produced from cyclohexane, the commercial process comprising the following stages (i) through (iii) as follows:
• (i) oxidation stage wherein cyclohexane is oxidized to provide a stream of cyclohexanol, cyclohexanone, and other byproducts,
• (ii) decanting stage wherein the stream of cyclohexanol, cyclohexanone, and byproducts produced by the oxidation stage is subjected to caustic treatment to remove alkali-soluble waste material thereby obtaining KAOW from the post-oxidation stream, and
• (iii) distillation stage wherein the cyclohexanol/cyclohexanone/byproduct stream treated in decanting stage (ii) is provided into at least one separation column for recovering any residual cyclohexane or for removing high-boiling point material from the cyclohexanol/cyclohexanone/byproduct stream;
• wherein the KAOW byproduct removed from the decanting stage (ii) comprises at least four sodium compounds selected from the group consisting of sodium hydroxide, sodium carbonate, sodium bicarbonate, sodium formate, sodium butyrate, sodium caproate, sodium glutarate, sodium adipate, sodium valerate, and sodium malonate, and derivatives thereof;
• and
• wherein the above components (A) and (B) are provided in the weight ratio (A:B) of 25-75:75-25.
