Abstract.The article presents our experience in the construction and quality control of building frames of two high-rises in the complex "OKO" of MIBC "Moscow-City" of high-strength concrete of six classes based on organo-mineral modifiers. The technology of construction of structures made of self-compacting concrete mixtures considers the increased temperature of concrete curing, which is achieved due to heat dissipation (self-heating) of massive vertical walls and columns and as well as due to electric curing of thin-walled beams in winter period. This technology made it possible to accelerate the turnover of formwork and structure loading, and thus to provide the specified time and high quality of construction workmanship. The quality control system of high-strength concretes according to GOST 31914 has given not only objective information on its strength, but also helped to prevent rejects and to control the quality of concrete when constructing unique structures and facilities.
Key words: high-rise building, reinforced concrete building frame, high-strength concrete, self-compacting concrete, îrgano-mineral modifier, concrete quality control. - REFERENCES
