| titleOfInvention | Method and apparatus for checking water-tightness of specimen of concrete |
| abstract | The invention relates to non-destructive testing by an acoustic emission method and can be used to determine the properties of concrete. The purpose of the invention is to increase productivity and accuracy by eliminating the measurement of water leaked through a sample. Sample 1 is exposed to water with stepwise increasing pressure and acoustic emission levels measured by receiver L are measured. Pressure and time are recorded at which acoustic signals were generated. emissions, and water pressure and the point in time at which the acoustic emission signals ceased and the entire sample was leaked. According to the measured data, water resistance is calculated. 2 cpf-ly, 2 ill., 1 tab. |
