How one applies the results obtained using this standard is beyond its scope. Standard triaxial cells and accessories The cell essentially consists of a transparent polycarbonate chamber which has a piston assembly asrm to the top and a double flange base fit to the bottom.

The specimen is axially loaded at a constant rate of axial deformation strain controlled. Therefore, if several specimens of the same material are tested, and if they are all at approximately the same water content and void ratio when they are tested, they will have approximately the same unconsolidated-undrained shear strength.

Soil mechanics – Triaxial Cells: Each test requires a list of accessories depending on the type of test and on the reference standard. The values stated in inch-pound units and given in parentheses are approximate.

Active Risk Management

Three or six simple thumbscrew are used to clamp the upper part of the cell to the base, which make assembly and disassembly a very quick and Referenced D8250 purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

ASTM D2850

In this test method, fluid flow is not permitted from or into the soil specimen as the load is applied, therefore the resulting pore pressure, and hence strength, differs from that developed in the case where drainage can occur. Installed on a PC communicating with the system over a fast Ethernet connection, the software can be used to configure the system scalibrate transducers, specify test parameters, set EmS technology is environmentally friendly and clean to operate, requiring no compressed air or hydraulic oil.

Your Alert Profile lists the documents that will be monitored. 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.

Specimens are subjected to a confining fluid pressure in a triaxial chamber. This test method provides for the measurement of the total stresses applied to the specimen, that is, the stresses are not corrected for pore-water pressure.
