EFFECT OF OILING UP ON ACOUSTIC EMISSION DETERMINED FAILURE OF CONCRETE

摘要

Results of research into the pattern of the stress failure of different grades of concrete oiled up with mineral oil are presented. Acoustic emission was the investigative method. The values of initial stress σ_1 and critical stress σ_(cr) determined both for oiled up and oil-free concretes indicate clearly that oiling up affects significantly the process of their failure. Practical implications of the obtained results are discussed.
