Heavy Concrete

The invention relates to the area of manufacture of building materials, in particular to manufacture of heavy concrete. It is offered new material - heavy concrete, which contains metal filling compound with following structure (on weight): 10-20 % ferrous or steel powder with the size of particles 15 100 micrommeters, 20-30 % steel rolling scale with the size of particles 5 20 micrometers, 50-70 % steel waste from sheet punching with the size of particles 1,0 5,0 mm. The received concrete has density from 3000 to 4500 kg/m3 and strength on compression after 28 days up to 50 MPa. A waste formed on filters in metallurgical manufacture can be used as an iron powder. The offered decision in comparison with known allows to receive following advantages of a material: technical (it makes possible to manufacture a material with the raised density and stability against radiation); economic (it makes possible to get lower cost of a material due to use of waste of metallurgical and machine-building manufacture); ecological (it makes possible to use production wastes rationally for manufacturing products with high technical parameters and provide radiological protection).
