Print and complete the following order form. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. It includes procedures for both intact rock strength and sliding friction tests which can be performed on specimens that are homogeneous or have planes of weakness, including natural or artificial discontinuities.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. The normal loading system is complete with an adjustable low friction pressure maintainer to absorb volume changes of the specimen during the shearing action and to ensure a constant vertical stress.

It includes procedures for both intact rock strength and sliding friction tests, which can be performed on specimens that are homogeneous, or have planes of weakness, including natural or artificial discontinuities.

Reporting of test results in units other than SI shall not be regarded as nonconformance with this test method. Please contact a CTLGroup chemical services representative or Project Manager to discuss your individual project needs and testing response times.

However, a clean, open d560 may be free draining, and, therefore, a test on a clean, open discontinuity could be considered a drained test. The shear box consists of two halves, the upper being connected to two rams for reversible shearing action and the lower connected to a ram for normal load application. Sliding on and shearing of the asperities can occur simultaneously. Reliable results depend on many factors, Practice D provides a means of evaluating some of those factors. Only one discontinuity per specimen can be tested.

Two versions are available:. The actual contact areas during testing change, but the actual total contact surface is unmeasurable.

Users of this standard are cautioned that compliance with Practice D does not in itself assure reliable results. Link to Active This link will always route to the current Active version of the standard. Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. However, a clean, open discontinuity may be free draining, and, therefore, a test on a clean, open discontinuity could be aztm a drained test.

Displacement and load readings shall be acquired by suitable datalogger that has to be add as accessory. Relationships derived from the test data include shear strength versus normal stress and shear stress versus shear displacement shear stiffness. During the test, shear strength is determined at various applied stresses normal to the sheared plane and at various shear displacements.

The actual contact areas during testing change, but the actual total contact surface is unmeasurable. Two set of cables are required. Instructions Samples should be concrete or rock cores with a diameter no greater than Historical Version s – view previous versions of standard. It is beyond the scope of these test methods to consider significant digits used in analysis methods for engineering design.

Rock shear box apparatus

Samples should be concrete or rock cores with a diameter no greater than ASTM D Use This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens. The test is usually conducted in the undrained state with an applied constant normal load. Only one discontinuity per specimen can be tested.

Therefore nominal area is used for loading purposes and calculations. The apparatus consists of a shear box designed to accept samples not larger than x mm, or alternatively cores up to mm dia. When the normal load is large enough to completely restrain dilation, the shear mechanism consists of the shearing off of the asperities.

Discontinuities may be open, partially or completely healed or filled that is, clay fillings and gouge. Shear box made in aluminium alloy Maximun axial and shear load capacity: Examples of an artificial discontinuity include a rock-concrete interface or a lift line from a concrete pour. This test method establishes requirements and laboratory procedures for performing direct shear strength tests on rock specimens.

The test is usually conducted in the undrained state with an applied constant normal load. Pervasive discontinuities joints, bedding planes, shear zones, fault zones, schistosity in a rock mass, and genesis, crystallography, texture, fabric, and other factors can cause the rock mass to behave as an anisotropic and heterogeneous discontinuum.
