- A pumpable slurry of neat cement or a mixture of neat cement and fine sand, commonly forced into a borehole to seal crevices in a rock to prevent ground water from seeping or flowing into an excavation, to seal crevices in a dam foundation, or to consolidate and cement together rock fragments in a brecciated or fragmented formation. also called cement grout.

Grout core, английский

- A machine that mixes the dry ingredients for a grout with water and injects it, under pressure, into a grout hole. compare grout machine.
Grout machine, английский
Grouting machine. a mechanism by which grout may be pressure-injected into a grout hole. the machine is essentially a closable cylindrical container large enough to hold the neat cement slurry made with one bag of cement. the slurry is placed inside the container and compressed air or steam allowed to enter the top of the container forcing the slurry out of the bottom of the container through a quick-opening plug valve into the grout pipe and grout hole. the process is intermittent, requiring the refilling of the container after each batch of slurry has been ejected. compare grout injector 2.
