Road construction: road damage caused by snow and ice load on the local road network. A polymer dispersion with additives based on nanotechnology could double the shelf life of at least roads. In the renovation of the Brenner motorway, the system has already proven. Also shows great interest in Russia. Local universities came to positive test results.
Until the summer, the stadiums for the Euro 2012 football championship, which Poland and Ukraine align together, be largely completed.Therefore stand in the western Ukrainian Lviv (Lemberg), despite the winter excavators and cranes still. The work on the go, this is also true for the access roads to the stadium, the 33 will accommodate 400 spectators.
Thanks to German nanotechnology, roads and paths are even built yet, when the mercury drops to -12 ° C in the basement.
The company was established in late 2009 and is specialized in research, development and application of nanotechnological procedures that are used in particular in the fields of construction, corrosion and fire protection.
Renner was promoted to the patented product Nanoterra soil (NTS), which was already the Brenner motorway and the renovated now to help in the Ukraine, to meet the requirements of the European Union of Football Associations.Thus, the Ukrainian government contractor Altkom after positive tests at the University of Kiev has decided to use the special material from Germany. Initially planned areas of 200 000 m 2 ; around the stadium.
NTS is a water soluble, environmentally neutral and non-toxic polymer additive based on butadiene, the nanoscale silica particles are added.Because of their size and especially the extremely large specific surface, these silicate in a position to make stable, cotton-like and very delicate structures that support the resulting soil structure and thereby increase the strength of the roadbed as well as base layers in the superstructure.
As an additive in concrete, asphalt roads or building material filled with the dispersion of its extremely high creep even the smallest pores of the nanomaterial. In addition, the polymer chains which give the elastic properties of soil and water repellent effect.
As a result, soils are so treated because of low water absorption, very resistant to frost.”The increased use of roads according to the duration produced by a factor of two to five,” Vladimir P. Nosov of the Institute for Automobile and Road Construction at the Technical University of Moscow. NTS nucleus of the procedure, the treatment of soil or mineral materials by homogenization with the addition of hydraulic binder (typically cement) is water and the nano-additive.
For existing roads, the installation particularly easy on the surface to be renewed will be sprinkled dry cement, a large milling machine, wearing the old blanket from then.At the same time is it in the crankcase of the milling machine is injected into water-dissolved polymer additive.
“As the new mixture is homogenized very well, also the rebuilding of roads takes less time,” said Chairman NanoSky course. “Construction times and costs are reduced by 30%,” says Paolo Duinella, president of the Brenner motorway. A total of 8 km were rehabilitated here in 2006 on nanotechnology methods.”Although the installation take place in winter at temperatures down to -12 ° C and had traveled up to 7,000 trucks daily to haul, to this day show no damage,” says Duinella.
The NTS-process is characterized by the company says, not least for environmental compatibility and economy because locally available materials can be used – “no matter whether it is an old base course or desert sand,” said Gang. In this way, conserve resources and minimize transportation.
As many raw materials come from natural materials, soils and sand over clay and marl to soil excavation, road construction and recycling material in question. Against this background, the first church built in Germany Kissing “Nano means”.Because tractors, trailers and equipment are getting bigger and heavier, the maintenance of roads is increasingly expensive. NTS offers a cost effective alternative.
“Existing material can be completely recycled, we also save an incredible number of truck trips,” says Mayor Manfred Wolf’s foray, which will now be introduced even in the household of Kissing need.
On the highway, driveway or lane stadium – NTS is good for many tasks. This was demonstrated by the Universities of Moscow and Tyumen (Siberia) in a comparative test with ten different solutions from five countries in the NTS has performed best. Due to climatic and geological conditions, Russia has certified the nano additive from Germany already – in the interest of stable and hardy streets. After the second harsh winter in a row in this country are likely to inquiries from Germany also increase.
