ceEntek Pte. Ltd. owns and controls all technologies, critical production and implementation steps for the production and application of ceUHPC™. This starts with carbon nano-material formulated to meet the requirements in UHPC and reaches to the on-site use of ceUHPC™.
ceEntek's optimized CNF for its UHPC reduces the number of ingrediences to just five: cement, sand, water, CNF, plastiziser!
Shortly following the discovery of carbon nano-fibers, their use in concrete was scientifically proven and realized in the laboratory. However, the technology could not be reduced to practice due to cost and implementation constraints. Today, carbon nano-fibers are used in many applications throughout various industries. Single-wall CNF are playing a major role in expanding present limitations in the semiconductor industry. Multi-wall CNFs are used in composites and batteries. However, CNF manufacturers have been slow adapting to specific end-users' needs. This prevented the breakthrough of CNF usage on a broad basis.
Ultrahigh Performance Concrete (UHPC) has been known since the early days of concrete, but found few applications only due to difficulties in sourcing the appropriate ingredients and complexities in the mixing process. Typically, UHPC systems require a complex blend of cements, fine aggregates, silica fume and various ad-mixtures. Due to this complexity, UHPC systems are blended in one or two locations globally, adding high logistics costs to the already high prices.
Based on huge infrastructure repair and replacement requirements in the developed world combined with an aggressive infrastructure build up in the developing countries, the demand for environment friendly long lasting solutions is rapidly growing. ceEntek's carbon nanofibers enhanced UHPC (ceUHPC™) meets the requirements for the most demanding applications at a competitive cost level.
ceUHPC™ can be prepared, used, and applied like normal concrete. Both precast and on-site fabrication is supported. The material is self-setting and self-leveling. No steam curing or enclaving is required to reach the desired strength and performance.
The use of Carbon Nanofibers/Nanotubes in UHPC had been scientifically proven shortly after the Japanese scientist Sumio Iijima (飯島 澄男 discovered them. However the homogeneous distribution of CNF/CNT in UHPC remained a problem and in combination with the high price of commercially available CNF/CNF limited the use to studies at Universities and Laboratories. Today ceEntek manufactures its own purpose grown CNF and made them the basis for a range of High-and Ultrahigh Performance Concrete Products.
