Patented modification of the surface of ordinary Portland cement with a 1.5-nanometer proprietary titanate coupling agent trade named Ken-React® KCM-3E produces a transformational Portland cement trade named Ken-Tec Portland cement allowing a 31% reduction in the water : cement ratio to equivalent flow (slump) while using significantly less time and energy to mix and providing new and novel material performance advantages important to sustainability and the infrastructure – such as: Greater compression strength; Efflorescence elimination; Faster mix cycles; Polymer compatibilization with epoxy, hydrocarbons such as oil, asphalt and plastics – 3-D Printing; Improved adhesion to PE reinforcing fibers and fabric; Adhesion to graphite, aramid, and nano-reinforcements such as bauxite, clays, graphene; rCB; etc.; Allow the incorporation of spent sulfur from refineries; Prevention of rebar corrosion; Less static build due to friction while flowing down metal chutes; More uniform cell structure in cement foam; More flexible structures for improved earthquake resistance; The creation of ageless and beautiful concrete structures. My Mission Statement for the last 46-years is “…To teach the more efficient use of raw materials through the use of titanates and zirconates.” The PowerPoint presentation will be an up-to-date review taken from over 450-ACS CAS abstracted “Works by S.J. Monte”, several thousand ACS CAS abstracts of work by others on “Ti/Zr Coupling Agents” – and their resultant commercial applications – and United States Patent 8591646 entitled, “CONSTRUCTION MATERIALS AND COMPOSITIONS FROM OIL CONTAMINATED PARTICLES” by Salvatore J. Monte. Concrete and polymeric compositions are often filled or reinforced with inorganic and organic fillers, pigments, fibers – some nano-sized. It will be shown that 1.5-nanometer heteroatom titanates/zirconates form functional atomic monolayers on the interface of non-silane reactive inorganics such as CaCO3, ZnO, TiO2, hydroxyapatite, metal powders, carbon black, CNTs, barium sulfide, Portland cement, boron nitride, etc. via proton coordination – absent the need for hydrolysis of surface hydroxyls as with silanes. The author solved the challenges of the U.S. DoD Insensitive Munitions Program. Specifically, unplanned detonation of LOVA propellant for the Abrams A-1A tank rounds caused tragic explosions. A 1.5-nanometer atomic monolayer of a phosphorus heteroatom titanate on the RDX explosive allowed highly loaded CAB plastic-bonded propellant to be produced that was both safer and more powerful than the prior art. The author’s United States Patent 6197135 entitled “ENHANCED ENERGETIC COMPOSITES” was held under DoD Secrecy Orders for over 14-years. Since the application of 1.5-nanometer titanium chemistry must be applied uniformly in atomic monolayers on to the surface of the Portland cement, a modern cement plant is needed. And the corporation owning the plant must be willing to license the technology and have a cement, mortar and concrete lab capability to take existing ASTM test procedures and modify them to conform to the new and novel nano-technology requiring significant change in construction industry concrete practices and culture. Due to the proprietary nature of the process and chemistry, a formal license agreement needs to be negotiated as the first step.
