... permeability were executed to define an optimum amount of bentonite and sand proportion for designing and constructing a better nuclear waste disposal facility. The addition of bentonite increases the geotechnical parameters such as maximum dry density, specific gravity, unconfined compressive strength...

... Abstract Determination of Unconfined Compressive Strength of rock is important in Geotechnical Engineering. Although laboratory test is the most direct way of rock compressive strength estimation, but UCS determination in laboratory is problematic if the rock masses are weathered because...

... The Correlation of Unconfined Compressive Strength with Dry Density and Grainsize for Different Aged Sedimentary Rock D. Wood & N. Shaw Parsons Brinckerhoff, Melbourne, Victoria, Australia Abstract: It is common engineering practice to estimate the Unconfined Compressive Strength (UCS) of a rock...

... and difficult to generalize. We studied the mechanical behaviour of gneiss samples of the Monte Canale unit (Central Alps, Italy). About 60 rock samples were tested under uniaxial and triaxial compression, and indirect tension tests. The samples revealed exceptionally low unconfined compressive strength...

... Terri Underground Rock Laboratory showed brittle rock mass behavior. In order to understand the observed failure mechanisms a detailed laboratory investigation has been initiated comprising servo-controlled direct shear and unconfined compressive strength tests. 1 INTRODUCTION The argillaceous rock...

... Abstract There are several empirical relations between the rock mass mechanical parameters (unconfined compressive strength, deformation modulus) and of the rock mass classification systems. These uniformly show increasing deformation modulus and compressive strength with the increasing...

.... The investigations done in this area are valuable but all works represent soft rock with a low unconfined compressive strength (< 8 MPa) and the model materials behave in a brittle manner under low confining pressures only. Rock generally is known as a brittle material and most rocks have a high strength...
