Expansion-Induced Crack Propagation in Rocks Monitored by Using Piezoelectric Transducers
The objective of this study is to develop a new vibration-free excavation method based on vermiculite expansion for rock cracking and to evaluate the performance of the heating system via elastic wave monitoring. Natural vermiculites expand rapidly in volume when heated above 800 °C. MgO powder is u...
