Supply, Installation, Testing and Commissioning of Lateral stress testing machine 2.3 kN capacity For any soil, Cohesion (C) and angle of Internal Friction(Ø)are two important engineering properties, which indicate the shear strength of soil. These two parameters are required for design of slopes, calculation bearing capacity of any strata, calculation of consolidation parameters and in many other analyses. Direct shear test is used to predict these parameters quickly, especially in cohesionless soils. Reference:IS-2720(Part-13):1986(Reaffirmed- 2016)IS :11229, 2720 (Part 13) “Methods of test for soils: Direct shear test” This standard ( Part 13 ) covers the methods for determination of shear strength of soil with a maximum particle size of 4.75 mm in undrained, consolidated undrained and consolidated drained conditions. This test can be performed in three different drainage conditions namely unconsolidated-undrained, consolidated-undrained and consolidated-drained conditions. In general, cohesionless soils are tested for direct shear in consolidated drained condition. Suitable for operation on 220V, 50Hz, Single phase, AC Supply.
