| Research Abstract |
A series of experimental studies for the micro-restructuring of rocklike materials has been carried out. Various techniques to improve the physical properties of rocklike materials by reconstructing their microstructures have been developed, i.e., a method to change the rock strength by controlling of micro-cracking, a grout technique using microorganisms, a sealing technique using mineral separation from the ground water and so on.
