Analysis of the test methods' standardization state for the basic characteristics of concrete

Abstract

Test methods for concrete are the basis for determining key characteristics in the design of concrete and reinforced concrete structures and their quality control. The ongoing updating of standards and regulatory documents in this area requires a systematic analysis of the entire regulatory framework in this area: there is a certain amount of requirements duplication in the international and national standards. At the same time, there are differences with international standards in the field of concrete testing methods, including non-destructive strength testing. This complicates the overall harmonization of the regulatory framework in terms of the design and construction of concrete and reinforced concrete structures. There are some gaps in the national regulatory framework, for example, on the test methods for fiber-reinforced concrete. The article presents the results of the monitoring and analysis of the national regulatory documents system in the field of concrete testing methods for the main characteristics of concrete. Priority areas for further research to develop test methods and standardize them formulated.
