Uses of non-metallic construction materials

RUBBLE FROM DENSE ROCKS is applied in road construction, by production of construction works, as filler to monolithic, modular and ferro-concrete designs. Distinctive property of rubble of all fractions is the cubical form of grains. It is reached by application in technological process of crushers of shock action. When using such rubble in road construction ability of a paving to maintain high loadings increases.

RUBBLE of fraction of 25-60 mm is applied to a bed of a railway. The combine "Uralasbest" the first in Russia received on rubble of 25-60 mm the certificate of conformity of the Register of certification on federal railway transport. Long-term operating experience and researches of experts showed that the bed from rubble of 25-60 mm can successfully be applied both at a section design of a way, and at non-section with railway cross ties. On way sites where our rubble is applied, costs of the current maintenance of a way decreased, the periods between repairs increased, repair cost decreased. Our rubble has low specific electric conductivity (0.0943 Ohm/m, norm of 0.32 Ohm/m). Use of our rubble as a bed and in protivopuchinny pillows allowed roads of the Urals and Siberia it is essential to reduce extent of sites with seasonal deformations of a way.

STONE from ROCKY BREEDS is issued in the form of fraction of 60-150 mm and it is applied to the laying of the bases, walls (external and internal), at construction of hydraulic engineering constructions and other massive concrete and ferro-concrete constructions, for decorative furnish of buildings and constructions.

MINERAL MIXES are applied during the manufacturing of asphalt concrete and asfalt mixes.

RUBBLE-SAND MIXES are applied to the device of coverings, the bases and additional layers of the bases of highways and airfields, for strengthening of roadsides of highways.

COARSE-GRAINED GRIT is applied by production of the soft roof to roofing material booking. It allows to increase indicators of durability and covering service life.
