Measuring method of the alkali-silica reaction in concrete by means of continuous sound emission analysis and ultrasound measurements

This invention relates to the combination destructive test for test specimens under simulated accelerated aging conditions. In particular, the present invention relates to the assessment of internal structural changes by means of continuous non-destructive measurement in concrete under conditions provoke an alkali-silica reaction (ASR). A continuous strain measurement and a continuous acoustic emission measurement with ultrasound test method is combined.
