Abstract:Damage of concrete is quantitatively estimated by applying AE rate-process analysis and damage mechanics. Controlled-damage specimens are prepared by freezing-thawing and carbonation. AE behavior in the compression test is analyzed as the rate process. From damage mechanics, a damage parameter is estimated. Using these parameters, compression behavior in concrete is analyzed quantitatively. As a result, it is demonstrated that the degree of damage is estimated quantitatively. Key Words:AE rate-process analysis, Damage mechanics, Freezing-thawing, Carbonation
