The most common method is to use cylinder cores drilled off the structure. Momber (b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Sealing of boreholes and underground excavations has not received much engineering attention until fairly recently. The growing awareness of and sensitivity to environmental concerns of the technical community as well as of the public at large has resulted in an increasing recognition of the fact that these geological penetrations may have an environmental impact.

Other in-situ tests include the static cone test, pressure meter test, vane shear test, and the borehole shear test. They provide soil strength values, such as cohesion, angle of internal friction, and shear strength.

Bearing is greatly increased when the internal tip plugs, due to the internal shear shear. Recent studies show that internal plugs of clay may not form in large diameter (greater than 2 m), open open--ended tubular piles when driven by rapid blows blows.

Push-out test mechanical interactions 29 The objective of this study is to determine the strength of cement grout borehole plugs in welded tuff cylinders as measured through push-out tests.

The push-out test involves the use of a steel rod to dislodge experimentally a cement grout plug emplaced within the coaxial borehole of a hollow rock 5/5(1). Examples have recently been collected and documented in which cemented borehole plugs have disintegrated and disappeared because of leaching of the cementitious material, usually by sulfate-rich or acidic water (see Section D).

In response, a number of cements that are resistant to sulfate attack have been developed. Bond strength is more dependent on consistency than the amount of water in grout; a wetter grout bonds better than a very dry grout.
