Development of a method to evaluate applicability of cementitious materials based on the implications for long-term safety has been performed considering the use of cementitious grout materials for reduction of water leakage during the stages of drilling of drift and implementation. In this study, an approach to evaluate the effects on alteration behavior of rock, the status of development of necessary model and database and a test case for evaluation are presented.
