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.

Standard - IS:1791:1985 The Concrete Mixer has been designed for mixing small quantities of concrete used in preparation of concrete cubes, for testing in laboratories. The purpose of the mixer is to smear mechanically the aggregate surface with cement paste uniformly & produce a mix of uniform consistency. This in turn gives consistent quality of cube specimens when casted in the moulds. The Concrete Mixer developed is transportable on wheels. The design of mixing paddles ensure uniform & efficient mixing of cement & aggregate both in dry & wet conditions. This machine is suitable for aggregate size upto 20mm. The equipment can also be put to use for mixing of any other material in dry / wet conditions. The arrangement helps the operators to access the pan contents conveniently & emptying the mixture after completion of the operation. The drum is driven off the ribbed base. The lid with mixing paddles clears off the top of the drum to provide maximum access to the operator.Specification:Mixing Capacity: 40 ltrs, Overall Dimension : 910mm X 875 mm X 1250mm, Motor : 3 HP, Drum RPM: 24 RPM, Special Features:Portable & Compact, Adjustable Blades, Simple to clean & maintain, Easy to operate, Suitable for operation on 440V, 50Hz, Three Phase, AC supply.
