MORDOVIAN SCIENTISTS HAVE DEVELOPED A LIGHTWEIGHT VERSION OF CONCRETE FOR THE CONSTRUCTION OF THERMAL AND NUCLEAR POWER FACILITIES
Scientists of the Mordovian State University named after N.P. Ogarev have developed lightweight structural and thermal insulation concrete with increased water resistance and frost resistance, reduced shrinkage deformations by half, high strength with reduced density and thermal conductivity. This is reported by the official website of the university.
The material can be used for the manufacture and repair of reinforced concrete products and structures - external walls, columns, beams, slabs, etc., used in the construction of high-rise and large-span buildings, the construction of bridges, roads, airfields, underground and hydraulic structures, oil and gas platforms, thermal and nuclear power facilities.
Lightweight concrete weighs 1.5-2 times less than traditional heavy concrete, while it has greater strength. The authors of the project achieved this by including energy-efficient porous aggregates in the composition of lightweight concrete, as well as organomineral additives of strengthening and expanding action based on local raw materials.
In comparison with known analogues, the main advantages of the developed technology are: multivariate compositions, reduced cement capacity and material cost, achieved by involving natural mineral raw materials in the formulation, common in many regions of the Russian Federation.
This material was developed within the framework of the strategic project «New Generation Materials and Energy Saving» under the program of the Ministry of Education and Science of Russia «Priority 2030».
