The Unconfined Compression Test Apparatus for soil includes uniaxial compression test in which the test specimen is provided with no lateral support while undergoing vertical compression. The test measures the unconfined compression strength of a cylinder of cohesive or semi-cohesive soil and indirectly shearing strength. The shearing strength of the soil is generally taken to be one-half of the unconfined compression strength. The unconfined compression test apparatus is used normally on an undisturbed sample with its natural moisture content. It may also be performed on remolded samples to evaluate the consequences of disturbances and remolding.
Unconfined Compression Test Apparatus is normally useful in soil mechanics laboratories. The unconfined compression test is the simplest and quickest method for evaluation of the shear strength of cohesive soil in the laboratory or in the field. The results from compression test apparatus are widely used in ascertaining the relative consistency and sensitivity for estimating the ultimate bearing capacity.

The Direct Shear test apparatus consist of a square or circular box divided into two halves. The specimen, contained in the box, is subjected to a constant normal load while an increasing horizontal force is applied to one of the sections of the shear box. This force causes a shear failure along the juncture between the box sections of this. The shear force and the normal load are measured directly. The rate of strain is adjusted by the speed of the horizontal force applied. The loading unit has V-strips on which the shear box housing rests. The load yoke in these direct shear test apparatus helps counter balance the loading system. The lead screw connected to the shear box housing helps application of shear stress.
Direct Shear Test Apparatus comprises of Direct Shear Box assembly for 60mm x 60mm x 25mm thick specimen, Shear Box Housing, Specimen cutter, Loading Unit with a capacity of 8kg/cm2, set of weights to give normal stress of 3kg/cm2, Proving Ring duly calibrated by Nccbm (Govt) of 2.5kN (250kgf) capacity & 2 (Two) Dial Gauges 0.01mm x 25mm travel. The load yoke with direct and through level system for applying normal load upto 8 kg/cm2 capacity, fixtures for proving ring, brackets for holding consolidation and strain dial gauges are also provided in these direct shear test apparatus.
Specifications:
- Max. Shear Force: 1.8 kn
- Measuring Range of Vertical Deformation: 0~10 mm
- Measuring Accuracy: +/-1%
