摘要

Applications of acoustic emission (AE) to structural integrity of concrete are summarized, dealing with both fresh and hardened concrete. Under mixing concrete, AE activity is applied to estimate the consistency. After hardened, in a uniaxial compression test, AE activity is modeled by the rate process theory and is correlated with the damage degree. For inspection of reinforced concrete (RC) members, the damage is qualified, based on Kaiser effect. Following the theoretical treatment, identification of cracking mechanisms by SiGMA procedure is discussed. Thus, AE characteristics of concrete are clarified from the fresh state to the damaged, and their applications to structural integrity of concrete structures are demonstrated.
