Abstract. The experience in construction of reinforced concrete monolithic slabs made of light concretes with the use of bearing reinforcement of increased rigidity is presented. As a result, a significant reduction in costs was reached comparing with slabs made of heavy concrete without pre-stressed reinforcement. The use of pre-stressed reinforced concrete in the monolithic construction as a structural material opens practically unlimited possibilities of planning of an internal space that makes it possible to design and construct buildings and structures with a variety of architectural appearance due to the wide range of variations in the shape of the building contours in a horizontal section. This technology can be used when constructing objects for various purposes - residential, office, industrial, warehouses, trade, etc. Comparative efficiency was calculated according to the generalized data of construction of twenty objects of different functional purposes.
Key words: pre-stressed concrete, external reinforcement, friction support, high strength bar, light concretes, expanded clay filler. - REFERENCES
