Nebraska located company (US) has developed a method enabling the construction of extremely strong buildings using precast concrete structures reinforced with basalt composites – mesh, rebar, and fiber.

The method is based on a new material that Rod Russell, the project head and CEO of
Rust and the difference in expansion coefficient between steel and concrete lead to the eventual decay of the structure. But basalt fiber has the same expansion coefficient as the concrete. Using the mixture of high tensile-strength rebar, mesh, and fiber, Russell said the product is a tenth of the weight, but three times as strong.
We actually believe we can build houses that last for thousands of years,
The new hybrid components of basalt and lightweight cellular concrete will make the construction easier, and the full-strength concrete columns make the structure tornado and wind-resistant. He said the lightweight concrete material has thermal resistance, meaning it doesn’t transfer heat and cold like regular concrete.
The USA is not the only country that uses basalt fiber reinforced concrete. For the Swedish marina builder SF Pontona, this material has become an ideal solution. The Project BasFlair of the Institut für Textiltechnik (ITA) of RWTH Aachen University, which replaced expensive and energy-intensive carbon fibers with basalt fibers in textile concrete, was recognized as part of the German climate initiative.
Experimental researches conducted in different countries worldwide confirm the feasibility of using basalt fiber reinforced concrete for both underground structures and ground structures in various building elements.
