Constructions of monolithic concrete and reinforced concrete. Rules of production and acceptance of work (About the draft of code of practice)
The draft of the developed code of production rules, as well as control and acceptance of works for the construction of buildings and structures from monolithic and reinforced concrete structures, developed in the advance of SP 48.13330; SP 63.13330: SP 70.13330 is described. The code of rules consists of sixteen sections containing general requirements, requirements for concrete mix, reinforcing, formwork and concrete work. Also, the requirements for the care of hardening concrete in the climatic conditions, to the acceptance and assessment of the compliance of the work performed and the quality of the structures are contained. For the first time, a number of separate requirements have been introduced to reduce thermal stresses in the process of maintaining concrete and to estimate the diffusion permeability index in concrete of carbon dioxide. The introduction of the developed norms into the general system of normative documentation in the field of concrete work will allow the builders and designers to ensure compliance with the specified design parameters and the durability of structures from concrete.
