Paper presented at the ISRM International Symposium - 8th Asian Rock Mechanics Symposium, October 14–16, 2014
Paper Number: ISRM-ARMS8-2014-246
... Abstract The authors proposed a new rock mass classification named as Rock Mass Quality Rating (RMQR), which consists of six main input parameters, quantifies the state of rock mass and helps to estimate geomechanical properties (UCS, cohesion, friction angle, deformation modulus, Poisson's...

However, researchers focus more on simulating the moisture transfer or suction evolution during the drying process of soft rocks and contribute less on drying shrinkage estimation. Hence, an existing micromechanical model which was used to analyze the drying shrinkage...
