Abstract:
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. 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.

The fundamentals of the research have been described in an article "Hybrid wood-polymer composites in civil engineering" at the Magazine of Civil Engineering.
