... plugs are 2.5 - 5 cm long and 2.5 cm in diameter. They are cleaned in a solvent extractor, flushed with demineralized water to remove residual salt and then oven-dried at 110°C. The cores are then geometrically measured and weighted and their porosity determined under laboratory conditions. Tests...

... ABSTRACT New design concepts, including the application of high pressure epoxy grouting techniques has been successfully employed for the construction of concrete plugs for water pressures up to 965 metres at Norwegian hydropower projects. In addition to hydropower plants, the developed...

... ABSTRACT: For rock stress measurement, a borehole is commonly drilled and sensors, composed of photo elastic borehole plugs, flat jacks, vibrating wire gauges or load cells, are inserted. Conventional sensors generally suffer the shortcoming of being expensive and difficult to install and use...

.... The central fault Which runs little askew to the dam, axis containing clay gouge and crushed rocks was treated by a concrete plug followed by grouting down to 10 m extended below the plug. The upstream, fault at the contact of the two rock formations was treated by high pressure grouting down to 45 m...
