Sika

The Sika company is founded in 1910 in Switzerland. Sika is the international chemical concern on production of materials and technologies for construction and transport mechanical engineering. Manufacturing enterprises, scientific laboratories, the centers of technical support and the trade missions in 90 countries of the world are a part of the company. In the company more than 16,000 employees work. Relying on long-term experience in the solution of different difficult tasks and the wide range of materials, Sika proposes complete solutions and systems practically for all construction objects in different parts of the world. Sika – the innovator in creation and use of many construction materials and technologies. The active position of Sika opens the wide horizons not only for the employees, trading partners and clients, but also for the construction industry in general. In Russia the Sika company works since 2003, has some plant on production of polikarboksilatny air, three plants on production of additives in concrete, two plants on production of dry construction mixes and five branches in different regions of the country with the central office in Lobnya of the Moscow region.

2016: Repair expenses of bridges in Russia will be cut down for 30-40%

The innovative technology of ulevolokonny gain will allow to reduce costs and terms of carrying out repair work of road constructions. According to preliminary estimates the term of maintenance free operation of the constructions strengthened by carbon fiber will be at least 25-30 years that by 1.5-2 times longer than other methods of gain.

Federal State Institution Uprdor Moskva-Volgograd, the subordinated organization of Rosavtodor, finished in the spring of 2016 carrying out experiments on implementation of the innovation construction materials on objects of road infrastructure. According to the results of an experiment the organization made the decision to implement in workflows one of the last developments of the construction industry – the Swiss technology of carbon fiber gain Sika CarboDur. Thanks to this development the term of repair of bridges, overpasses and other road constructions can be reduced by 2–3 times, and expenses on their further operation can be reduced twice.

Composite materials are applied by Federal State Institution Uprdor Moskva-Volgograd in the test mode since 2013 and were tested at construction and repair of road constructions on federal highways in the Tambov, Volgograd and Ryazan regions. The Sika CarboDur system was used for repair and gain of steel concrete support and flying structures of bridges.

Sergey Senibabnov, head of department of quality control of Federal State Institution Uprdor Moskva-Volgograd: "In comparison with constructions from metal, elements of road arrangement from composite materials have several advantages - it is capability to repeat practically any forms of construction, high strength, rigidity, small weight, technological effectiveness, immunity to aggressive external factors, durability. One of the most important factors – products from composites do not require leaving in use, they are not subject to corrosion, they do not need to be painted and consequently, additional finance costs are not required".

The technology of ulevolokonny gain Sika CarboDur not only allows to reduce repair terms by 2–3 times and to increase possible load of the building of 30–40%, but also to prolong operation of bridges for 25–30 years that on average for 10–15 years longer, than gain by steel holders.

Now the quantity of bridge constructions in Russia for whom the Sika systems were already tested exceeded 200 objects. Among them: the bridge to Russky Island in Vladivostok, Palace Bridge in St. Petersburg, a series of road constructions on MKAD and a TTK in Moscow, the combined highway Adler is Alpika-service in Sochi. At the moment the technology has rather fine-molded character and is used in those cases where use of other methods of gain is difficult.
