The materials for underground construction, underground construction.

The material with which to build underground structures, must have a high resistance, water resistance, erode, frost resistance and fire resistance. Due to the complexity of reconstruction of underground facilities, their service life should be longer than the land-based structures, respectively, the materials for the manufacture of such structures needs to be better. Materials which meet such requirement are: steel, cast iron, concrete and reinforced concrete. When erecting concrete structures concrete its hardness should not be less than “B15”, and the thickness of load-bearing elements not less than 20 cm. For prestressed concrete structures the concrete grade shall not be less than “B25”. Mark of concrete on water resistance should not be less than “B-6” for structures located in soil moisture hanged. Estimated supports of concrete in concrete and reinforced concrete structures take accordingly to the current normative document. Continue reading
