Standard Test Method for Torsional Ring Shear Test to

5;4 The ring shear device keeps the cross-sectional area of the shear surface constant during shear and shears the specimen continuously in one rotational direction for any magnitude of displacement; This allows clay particles to become oriented parallel to the direction of shear and a residual strength condition to develop;

Slake durability apparatus, Rock mechanics testing equipment

This test method has been developed to ASTM D4644 for assessing the deterioration of rocks over a period of time when subjected to water immersion. The apparatus consists of a motorized drive unit mounted on a baseplate and connected to two or four drums which rotate at a speed of 20 r.p.m.

Direct Shear Test: Apparatus and Procedure | Shear Strength

4_ The test is continued till the shear load reaches a maximum value and then decreases_ 5_ The shear load is then released` and the proving ring and deformation dial gauges as well as the shear box are dismantled_ 6_ The test is repeated with three normal stresses of 100`200` and 400 kN/m 2_ Determination of Shear Parameters-

Direct shear test -

A direct shear test is a laboratory or field test used by geotechnical engineers to measure the shear strength properties of soil or rock material, or of discontinuities in soil or rock masses. The U.S. and U.K. standards defining how the test should be performed are ASTM D 3080, AASHTO T236 and BS 1377-7-1990
