A new system of building structures based on nanostrutured concrete
(Nanowerk News) Professor of the Institute of Civil Engineering of Peter the Great Saint-Petersburg Polytechnic University (SPbPU) Andrey Ponomarev and a graduate student Alexander Rassokhin developed a new construction technology (Magazine of Civil Engineering, "Hybrid wood-polymer composites in civil engineering").

Scientists created several types of building blocks based on nanostructured high-strength lightweight concrete, reinforced with skew-angular composite coarse grids.
|
|
The development has unique characteristics, enabling the increase of load-carrying capability by more than 200% and decrease in specific density of the construction by 80%.
|
|
In addition, among the advantages, are resistance to corrosion, aggressive environments and excessive frost resistance.
|
|
Researchers calculated that the service life of the building structures, made with the use of this reinforcement system, will increase at least 2-3 times in comparison with its modern analogs.
|
|
"Such system allows to ensure the structure integrity even in conditions of seismic activity, since the load is distributed throughout the structure as a whole, and not by individual reinforcement bars.
|
|
The invention can be used in the construction of bridges and pedestrian crossings, non-metallic ships, low-rise residential buildings" says Alexander Rassokhin.
