Review of Ukrainian standard requirements for selecting the type of cement to ensuring the durability of reinforced concrete structures

Introduction. The post-war reconstruction of Ukraine is one of the most important stages in the restoration of a state that has suffered significant destruction and losses. Reconstruction requires a comprehensive approach to the problem of destroyed infrastructure and housing stock, in addition to financial investments. The solutions needed today are construction and production of building materials based on the principles of sustainable development. The best European practices and experience should be incorporated. Problems. The European integration of the construction materials industry has been in the process of implementation in the form of Regulation (EU) no. 305/2011 [1], and from January 1, 2023, the Law of Ukraine "On placing construction products on the market" [2], implementing the provisions of Regulation (EU) no. 305/2011 [1]. At the same time, the previous national standards - the State Standards of Ukraine - are still in force in parallel with the newly introduced European standards. This makes it difficult for manufacturers, customers, construction companies and designers to use the regulatory documentation. This situation fully applies to producing concrete and cement used in general construction. Objective. To review the current Ukrainian standards that regulate the selection of the required type of concrete mixtures by designers and manufacturers of concrete mixtures cement to meet the durability requirements of concrete structures.
