Renewal of interstate standard “Concrete and reinforced concrete board stones”

Abstract

Introduction. For 35 years since the introduction of State Standard 6665-91, the regulatory framework for the design and production of reinforced concrete products has been significantly changed and supplemented. In this regard, an updated interstate standard for concrete and reinforced concrete side stones has been developed, taking into account changes in the regulatory literature.Aim. Familiarization of specialists in the design and production of concrete and reinforced concrete side stones with the updated State Standard 6665-91 in connection with the updating of the regulatory framework.Materials and methods. The information about the updated interstate standard State Standard 6665 "Concrete and reinforced concrete side stones. Technical conditions", which provides rules and requirements for the design, testing and manufacturing technology of concrete and reinforced concrete side stones.Results. As a result of the revision of the standard, stricter requirements for concrete have been established, the choice of reinforcement classes for reinforcing side stones has been expanded, which can significantly increase their durability.Conclusions. Updating the requirements for acceptance rules and control methods allows to improve the quality of factory production of precast concrete and reinforced concrete side stones.
