Particulate grouting has long posed challenges to those in the geotechnical field. But significant developments in the understanding of hydration and rheology control look promising. Modern geotechnical construction projects place increasingly challenging demands on particulate grout. Two significant challenges are hydration (setting and hardening of the mixture) and rheology control (consistency). Geotechnical projects also require higher degrees of washout resistance and formation penetrability. Recent projects in the U.S. have tested and are proving new developments in particulate grouting. These include The Deer Island Outfall Tunnel, Boston; Channel Tunnel, UK; Barrick Gold Mine, Elko, Nev.; and Inter-Island Tunnel, Boston.
