Iwatsuki, Teruki  ; Murakami, Hiroaki  ; Watanabe, Yusuke  ; Fukuda, Kenji

Drift closure test was carried out to understand the hydrochemical influence of cement materials to groundwater in Mizunami Underground Research Laboratory. In the end, the amount of cement material including portlandite to evolve the alkaline groundwater was quantitatively estimated 0.5mm depth of shotcrete.
