습식분쇄에 따른 그라우트재의 물성변화

To increase strength and durability of ground after grouting, it is good to use grout based on suspension type, but it tends to use grout based on solution type because of its eminent permeability. Nowadays, technology of particle acceleration that make material's permeability improved like grout based on solution type, and inexpensive compared with traditional ordinary cement are being required. For this reason, in this study, using wet milling system, physical property of materials according as manufactured factors were evaluated, such as w/c of particles before being milled, optimum milling capacity by controlling milling time and rpm, viscosity of materials, permeation coefficient, and unconfined compressive strength.
