Ultrasound propagation speed and mass changes by application of different accelerated artificial ageing tests in granitic materials [Dataset]
In this work the ultrasound propagation speed on the three spatial planes (Vx,Vy,Vz) and the weight loss/gain of three ornamental granites (Ávila, Spain) were determined before, during, and after being subjected to 90 cycles of three types of accelerated ageing processes (typical of cold regions): a...

| Resumo: | In this work the ultrasound propagation speed on the three spatial planes (Vx,Vy,Vz) and the weight loss/gain of three ornamental granites (Ávila, Spain) were determined before, during, and after being subjected to 90 cycles of three types of accelerated ageing processes (typical of cold regions): a) freezing/thawing and cooling/heating (T1), b) salt crystallisation (T2), and c) freezing/thawing and cooling/heating + salt crystallisation (T3). A three-way mixed multivariate analysis of variance (MANOVA) was used for data analysis. To determine the durability of the different varieties of granite against the accelerated artificial ageing tests studied, the estimated data of resistance to compression, obtained from the ultrasound propagation speed data, were determined. |
