COMPOSITE REINFORCEMENT IN THE CONSTRUCTION INDUSTRY: TRENDS OF EXPANDING USE

Abstract

Scientific and technical progress largely ensures the production and use of new effective building construction materials with predetermined properties. The article considers the prospects of using a relatively new modern material in construction - composite reinforcement (AC), which has a number of advantages compared to traditional metal reinforcement and at the same time is characterized by properties that limit its use in the production technology of modern concrete structures. In connection with a number of circumstances associated with the expansion of the operating conditions of reinforced concrete structures in highly aggressive environments, where it is difficult to ensure the corrosion resistance of steel reinforcement, composite reinforcement is used. The prospects of using composite reinforcement in ensuring the dielectric properties of some products and structures are shown. The global experience of using AK is summarized, the modern regulatory framework for its use in modern construction is given. It is shown that the use of AK on a par with steel reinforcement according to current standards regarding mechanical, technological and operational properties is sufficient to solve the vast majority of construction tasks. Reasons for the expansion of the use of composite reinforcement, taking into account the high energy intensity of traditional steel reinforcement and the inevitability of reducing greenhouse gas emissions in accordance with Ukraine's international obligations, are given.
