TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that perform high quality tests at high productivity levels. Soil asgm – Consolidation benches: Reliable testing depends on several factors; Practice D provides a means of evaluating some of those factors.

Reporting of test results in units other than SI shall ashm be regarded as nonconformance with this test method. This shear strength may be applied to field conditions where full drainage can occur drained conditions or where pore pressures induced by loading can be estimated, and the field stress conditions are similar to those in the test method.

Soil mechanics – Triaxial load frames: Using the pore-water pressure measured during the test, the shear strength determined from this test method can be expressed in terms of effective stress. With this equipment it is possible to perform the consolidation stage of three triaxial specimens at the same time for CU and CD tests in anisotropic conditions.

It is the responsibility of the user of this standard adtm establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.

Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: In this system, the pound lbf represents a unit of force weightwhile the unit sstm mass is slugs. After the density has been determined, the unit weight is calculated in SI or inch-pound units, or both.


ASTM D Standard

Note 1—If the strength is required for the case where the soil is not consolidated during testing prior to shear, refer to Test Method D or Test Method D Follow us YouTube LinkedIn. The load frame is built around a robust twin column It is beyond the scope of this test method to consider significant digits used in analysis methods for engineering design. This implicitly asfm two separate astn of units; that is, the absolute system and the gravitational system. 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 If Hydromatic standalone pressure unit is selected, a separate volume change device is not required.

Agencies which meet the criteria of Practice D are generally considered capable of competent testing. In this test method, the shear characteristics are measured under undrained conditions and is applicable to field astj where soils that have been fully consolidated under one set asgm stresses are subjected to a change in stress without time for further consolidation to take place undrained conditionand the field stress conditions are similar to those in the test method.

In addition, they are representative of the significant digits that generally should be retained. Link to Active This link will always route to the current Active version of the standard. Soil mechanics – Dynamic triaxial systems: Triaxial cell with accessories: Historical Version s – view previous versions of standard. Standard triaxial cells and accessories The cell essentially consists of a transparent polycarbonate chamber which has a piston assembly fit to the top and a double flange base fit to the bottom.


ASTM D4767

Data are automatically transferred to the PC in real time for live plotting and monitoring of the tests in progress. Generally, three specimens are tested at different effective consolidation stresses to define a strength envelope. Specimens are isotropically consolidated and sheared in compression without drainage at a constant rate of axial deformation strain controlled. Please contact us for a complete offer. The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used.

Template for data processing and reporting: It offer excellent reliability, accurate testing and lower maintenance requirements. Consolidation bench for triaxial cells The apparatus has been designed to reduce the testing time for triaxial tests, where only one compression machine is available.

Data acquisition can be shared with other soil testing equipment. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies or any consideration of end use.

Density is mass per unit volume whereas unit weight is force per unit volume. Standard triaxial configuration with built-in data acquisition can be used for performing additional tests such as CBR, Unconfined and CRS.

A typical standard triaxial system with external data acquisition system includes: The design of the cell ensure vertical alignement of the cell ram by clamping the Perspex wall separately from TRITECH original high-performance load frames for triaxial tests, ideal solution for advanced and research laboratories that want to perform high quality tests at.

Data acquisition is f4767 in the load frame; four channels are available for load, displacement, pore pressure and volume change.
