Information of Shear values plays an important role the design of sub-structures in determining bearing capacity of soils, design of retaining walls, instability calculation earth slopes etc. Various Shear Apparatus are available and Direct Shear Apparatus is one of them. In Direct Shear test specimen contained in a box is subjected to a constant normal load and increasing horizontal load is applied to the upper section of the specimen. Shear force and load are directly measured. For determination of the direct shear strength of soils on specimen size 60 mm x 60 mm x 25 mm.

Specification:

The apparatus comprises of the following:

Loading Unit: Supplied with load yoke with direct and lever system for applying load. Normal stress capacity 8kg/sq.cm. Load is applied either directly of through a counter balanced detachable lever. Provision is made for load to be applied either through a steel ball recessed in the loading pad or direct through a boss on the pre calibrated loading yoke. The loading unit is provided with V strips and roller strips for frictionless movement of shear box housing.
