Abstract
The performances of dry-grinding fine cemenT (DFC) in grouting procedure were experimentally studied. The measurement of its fineness and simulated test for injectability showed that this DFC could be used to inject rock mass with micro-fissure. In order to improve the grouting quality, the water-cement ratio and discarding time of slurry should be controlled precisely. If the water-cement ratio is over 2∶1 in slurry that is made from DFC, it is not suitable to grout. Finally, the influence of different mixing times on strength of hydrated cement made from the DFC is explained by microstructure analysis with SEM.
