IS 2720 : Part 11 : 1993 Methods of test for soils: Part 11 Determination of the Shear Strength Parameters of a specimen tested in inconsolidated, indrained triaxial compression without the measurement of pore water pressure

1 Scope

1.1 This standard (Part 11) describes the test for thedetermination of the compressive strength of a specimen ofsaturated cohesive soil in the triaxial compression apparatus underconditions in which the cell pressure is maintained constant andthere is no change in the total water content of the specimen (seeNotes 1 and 2).

Note 1 - In this standard the term 'sample' is used to denotethe soil submitted to the laboratory for the testing and the term`specimen' refers to a portion of the sample upon which the test isperformed.

Note 2 - The result of any test made in accordance with thisstandard requires interpretation in relation to the nature of thesoil and the way in which the specimen was obtained and prepared.

1.1.1 This test is limited to specimens in the form of rightcylinders of nominal diameter 38, 50, 70 and 100 mm and of heightapproximately equal to twice the nominal diameter (see Note). Incase of remoulded samples; ratio of diameter of specimen to maximumsize of particle in the soil should not be less than 5.

Note - The diameter of the specimen is to be selected havingregard to the character of the soil and the maximum size of theparticles present in the sample. Generally, a diameter of 38 mmwill be suitable for homogeneous fine-grained soils.
