Comparison of concrete creep test methods as per Russian and foreign normative documents. Part 2. Testing and processing of results

Introduction . The main approaches to long-term creep tests of concrete regulated by GOST 24544-2020, valid in the Russian Federation, as well foreign ISO, ASTM, and EN standards, are analyzed. Aim In this work, fundamental differences conducting following standards determined. These efforts essential urgent, since, order use test results obtained abroad Russia, it is necessary harmonize methods initial parameters (samples, measuring equipment, etc.). Materials article reviews testing procedures, controlled parameters, processing result; part 1 covered application, manufacturing process, sample fittings, preparation. Results comparable; however, they differ greatly from 24544 some respects, particular, regarding their installation equipment. Conclusion Further harmonization with aforementioned necessary.
