EXPERIMENTAL RESEARCH ON MECHANICAL PROPERTIES OF LIMESTONE AND SANDSTONE UNDER HIGH TEMPERATURE
QIN Ben-dong, HE Jun, CHEN Lun-jian
2009, 15(3): 253-261.
Abstract (278) HTML (136) PDF (478KB)(14)
Abstract:
The mechanical properties of limestone and sandstone under high temperature were investigated by the experiment device used to heat rock designed by ourselves and servo-control testing machine RMT-150C. The results show that the longitudinal wave velocity of two kinds of rocks gradually reduced with...
