Two largest overpasses of the Republic of Belarus were repaired with NCC materials

In July 2019, the Russian company NCC, a leader in the composites market, supplied CarbonWrap external reinforcement systems to the Republic of Belarus, which were used to repair the two largest overpasses in the country - "Baranovichi-Polesky" and "Western Bypass".

The inspection of "Baranovichi-Poleski" overpass revealed defects in beam concrete and above-normative deflections of the structure due to corrosion of the stretch zone reinforcement. As a result the decision was made to reinforce the span structures with special CarbonWrap Lamel T lamellae which are used for the structures of high responsibility. The necessary repair work was carried out by the state enterprise "BeldorNII". On completion of this work, on-site tests were conducted which showed that the parameters of the reinforced overpass span structures fully meet all the design requirements.

The second overpass - the "Western Bypass", passing over the railway tracks, was reinforced with the use of carbon plastic lamellae and fabrics on the basis of carbon fiber. The need for reinforcement at this facility was caused by significant defects, including cracks in some spans of the middle part, which arose due to violation of the pouring and formwork removal technology. All necessary repairs were carried out without stopping the railway trains.

About CarbonWrap

The CarbonWrap External Reinforcement System (ERS) by NCC is designed to repair and reinforce building structures in order to eliminate the effects of concrete destruction and corrosion of reinforcement, as a result of long-term exposure to natural factors and corrosive environments during operation. The experience of using CBA in the reinforcement of structures shows that this technology allows you to work in a short time, while the cost of an average of 15-20% below the cost of traditional methods of repair / strengthening.

Taking into account the given advantages, the materials of CarbonWrap system are highly demanded for the repair and restoration of structures on the territory of the Republic of Belarus.

About the Company

Nanotechnology Centre for Composites (NCC LLC) is the leading company on the market of composites, which performs the full cycle of development and production of polymer composite materials for various industries. The company performs design and strength calculations, material development, tooling fabrication, painting, assembly, prototyping, testing and certification. "NCC holds a significant number of patents for its products.

"NCC is a joint venture between the Fund for Infrastructure and Educational Programs (Rusnano) and DowAksa Advanced Composites Holdings BV (Dow Chemical), the company was established in 2012. Total investments, including the purchase of laboratory and production equipment, exceeded 2 billion rubles.

NCC employs 250 high-class specialists on the production area of 14 thousand square meters. The production itself is equipped with more than 100 units of hi-tech equipment and measuring devices.

Products

The basis of the range of "NCC" are:

Products for construction and infrastructure - external reinforcement system, guardrails, drainage gutters, transmission line supports, protective casings for gas pipes;

Mobile road pavements;

Equipment for cooling towers - sprinklers, water traps, support beams, pipe systems, walking bridges;

UAV products - tooling, assemblies, fuselage parts;

Products for transport, including exterior and interior cladding panels for railcars.

At the same time, NCC implements unique projects to order. For example, the company designed and manufactured a carbon plastic simulator body for pilots by the order of CNTU "Dynamics". Traditionally, such simulators are made with a significant amount of metal, but this NCC product is made almost entirely of carbon fiber, which significantly reduces the weight of the simulator and decreases the load on the mobility nodes. Such an updated design allows for a more realistic flight simulation.

NCC possesses two in-house test laboratories (general purpose and construction) with more than 60 units of measuring equipment. Thanks to such equipment, the company's laboratories are able to conduct a wide range of climatic, physical and mechanical, temperature and other tests for various types of products.

Export

"NCC has been actively developing its export activities since 2014. As of today, supplies of various company products are carried out to India, Kuwait, Mexico, and the USA.

The main export product of the company is the External Reinforcement System (ERS) CarbonWrap, designed for repair and restoration of reinforced concrete structures, which, apart from wide application in Russia, is also supplied to Turkey, Asia, USA, the Republic of Kazakhstan and Belarus, as well as to a number of European countries. With the help of this system it is possible to successfully and in a short time repair destroyed beams, slabs, columns, ledgers and any other reinforced concrete structures, including those that have lost their bearing capacity.
