ASTM D 2850 - 03a (Reapproved 2007) Standard Test Method for Unconsolidated-Undrained Triaxial Compression Test on Cohesive Soils

American Society for Testing and Materials (ASTM). Current edition approved Sept. 15, 2007. Published October 2007. 6 p. This test method covers determination of the strength and stress-strain relationships of a cylindrical specimen of either undisturbed or remolded cohesive soil. Specimens are subjected to a confining fluid pressure in a triaxial chamber. No drainage of the specimen is permitted during the test. The specimen is sheared in compression without drainage at a constant rate of axial deformation (strain controlled).
