The paper presents the test results for the use of the modified IADP (Identification of Active Destructive Processes) acoustic emission method to identify destructive processes that occur in unloaded early-age concrete. The results of the tests performed on 24 specimens made with limestone aggregate at varied conditions of curing and hardening and at the presence of reinforcement and additions, confirm the applicability of the method to identify destructive processes, such as microcracks formed in cement paste, growth of internal microcracks and formation of surface microcracks in unloaded concrete.
