Direct Shear Apparatus Manually — MOE Lab Tender Details

Direct Shear Apparatus Manually

Description: Shear values plays an important role in the design of sub-structures in determining bearing capacity of soils, design of retaining walls, instability calculation earth slopes etc. 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. ASTM D-3080
Specification: The apparatus comprises of the following:
Loading Unit:
load yoke with direct and lever system for applying load. Normal stress capacity 8kg/sq.cm. The loading unit is provided with V strips and roller strips for frictionless movement of shear box housing.
Shear Box Assembly:
Comprising Direct Shear box in two halves for a square specimen size 60 x 60 x 25 mm one pair of plain gripper plates, one pair or perforated gripper plates, one pair or porous stones, one top loading pad. Shear box housing: Accommodates the Direct Shear Box assembly. Complete with two ball roller strips.


Specimen Cutter:
For cutting 60 x 60 x 25 mm specimen from larger samples. Set of weights to give a normal stress of 3 kg/sq.cm.
