A bleeding examination and a flow characteristic examination of grout materials were performed to understand the fundamental characteristic of grout materials. Moreover, an injection experiment of grout materials which used a decomposed granite was conducted to understand the applicability of the analysis technique which introduced filtration theory. The results are as follows:<BR>1) When cement water ratio is large, a bleeding speed becomes slow, but the bleeding ratio becomes small.<BR>2) Plastic viscosity and yield stress become large with increase of cement water ratio. Particularly, plastic viscosity change greatly on <i>C</i> / <i>W</i> = 1 / 1.6. And as compared with yield stress, it is larger about influence on the discharge.<BR>3) Where a cement water ratio does not exceed <i>C</i> / <i>W</i> = 1 / 5, the clogging of the voids was done by a suspension custody. And where <i>C</i> / <i>W</i> = 1 / 3.5, that was done by a surface filter layer.<BR>4) The plastic viscosity measured using Brookfield viscometer is a result when some cement particles aggregate, and shows big value as compared with the theoretical relative viscosity.<BR>5) The result of injection analysis using the theoretical relative viscosity assumed that the cement particle is distributing completely is well as an experiment result in agreement. In the grout materials which flow the inside of the voids, it cleared that plastic viscosity follows the theoretical relative viscosity which the cement particles distributed.
