Abstract:

The results of acoustic-emission tests on young concrete specimens and concrete cores from airfield pavements indicate that the Kaiser Effect is not permanent in concrete. That is, there is a recovery such that load cycles applied subsequent to the initial load cycle will produce acoustic-emission signals similar to those obtained during the first load cycle. This report suggests, therefore, that the Kaiser Effect cannot be used to detect the maximum past stress in concrete which has not been subjected to a continuous stress.
