ceEntek Pte Ltd focuses on technologies required for the cost effective production of nano-engineered ultrahigh

performance concrete (ceUHPC™). ceEntek employs specialists in the area of carbon nano-material production, dispersion

of this material in water, ultrahigh performance concrete as well as applications of ceUHPC™. The company has close

technical relationships with leading universities and industrial partners in the above fields in Europe, the US, and Asia.

As a result, ceEntek developed an advanced ceUHPC™ system eliminating the handling, performance and cost barriers for

UHPC preparation, curing and usage. ceEntek’s low cost, low energy, high quality ceUHPC™ system does not only

outperform other UHPC systems in terms of physical strength, but shows extremely high resistivity against chemical

attacks, carbonation and moisture intrusion. This guarantees an extended useful life of ceUHPC™ based solutions.

“From bigger skyscrapers and readily transportable

prefabricated homes to lagoon cities, material pioneers -

like ceEntek - are placing Singapore at the forefront of a

looming global battle against overpopulation.”

Our Know-How and IP


ceEntek Pte. Ltd. owns and controls all technologies and critical production and implementation steps for the manufacture

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™.

CNF productionceEntek has developed a chemical free, scalable, one-step CNF production process synthesizing the product needed for inclusion into UHPC. No further treatment steps are required to ‘functionalize’ the CNF. ceEntek is using readily available carbon carriers in combination with a metal catalysts to produce CNF in a continuous process.

“Building a Lasting Future” ceEntek


A highly homogenous and stable dispersion in wateris the prerequisite for the application in concrete.

ceEntek produces hydrophilic CNF that can bedispersed in water by means of Ultrasound, HydroCavitation, or high-shear mixing.

The CNF specific surface chemistry results in achemical bond with the concrete paste during thehydration process. To enhance transportability andease of use, ceEntek developed a CNF based pastethat easily dilutes in the mixing water for the UHPC.

Nano engineered Ultra-High Performance Concrete

ceEntek Pte Ltd developed ce200™, a nano engineered ultrahigh performance concrete (UHPC) which is the basis for a

range of high performance cement based UHPC and HPC products for a wide range of applications. The development of

ce200™ represents a revolution to the worldwide concrete industry realizing the vision for a nano-fibers enhanced concrete

established 25 years ago. ce200™ and its derivatives can be blended and mixed using local materials extending the

geographical range for UHPC.

UHPC system

ceEntek has developed a ‘climate adjustable’ UHPC system as

the basis for CNF enhanced UHPC. This system provides the

physical and chemical features for the enhancement with CNF.

Base materials used for this UHPC system (cement and graded

sand) are all commercially available worldwide allowing for a

cost effective local implementation of ceUHPC™. To avoid long

term degradation effects of the UHPC as is typical for multi-

ingredients based products, ceEntek has limited the use of

ingredients and strictly follows quality control procedures.

Why use ceEntek?


ceEntek Solution

ceEntek has been able to overcome the limitations for carbon nano-fiber enhanced ultrahigh performance concrete. ceUHPC™

expands the horizon for UHPC in terms of performance, cost, ease of use, carbon footprint, and climate zone adaptation.

Easy to Prepare and Use

ceUHPC™ can be prepared, used, and applied like normal concrete. Both precast and on-site fabrications are supported. The

material is self-setting and self-leveling. No steam curing or enclaving is required to reach the desired strength and performance.

Environmentally Friendly

The cement content of ceUHPC™ can be limited by using pozzolanic cement replacements like GGBS (ground granulated blast-

furnace slag), RHA (rice husk ash), Fly-ash, and similar materials. Environmentally friendly, waste products or sustainable

aggregates can be used based on the performance level required. Due to its high strength per volume (up to five times higher

than normal concrete) and its lack of chemical additives ceUHPC™ has the lowest carbon footprint of all known UHPC variations.
