Electronic Triaxial Shear Test Apparatus (Motorised).

The settlement of foundations and changes in earth pressure due to movement of retaining walls or other earth supports, the yield of soil caused by application of load, are affected by the stress-strain relationship of soils. The experimental investigation for determining the stress-strain relation is usually carried out with Triaxial Compression Test. During the test, the soil samples gradually stressed up to failure. Generally speaking, Triaxial Tests are performed to stimulate different types of stress and drainage conditions that can occur in the sub-soil for simulating the effect of building construction, excavation, tunneling etc. Three different Triaxial Tests are usually performed for total and effective stress measurement. The 50 kN capacity machine, designed primarily for triaxial testing of soil specimens upto 100mm diameter x 200 mm long, comprises a rigid twin column construction with an integral fully variable. Models Available Digital Triaxial SYSTEMMicroprocessor controlled drive unit and LCD display with a touch sensitive keyboard. The machine is normally bench mounted for ease of installation and operation. The digital indication of the load, pressure and the strain are displayed on the front panel of the load frame. Selector switch has been provided to shift the digital indicator from load to pressure or to strain.

Proctor Compaction Test Apparatus.

Soil compaction is of utmost requirement for constructing earth fill for dams, canal embankments, reservoirs, highways, runways and railways. The relationship between soil moisture content and compacted dry density largely determine the construction specifications and quality control of compacted earth fill. To check the strength of the soil the density of the soil is taken into account and hence the quality control is checked otherwise.

Semi-Automatic Compactor.

Now a days almost every soil laboratory conducts compaction and penetration tests on soils. In both standard and heavy compaction tests the operator has to count the number of blows of the rammer on each layer of soil during compaction. A mechanically cum electrically operated semi-automatic compactor is therefore devised to eliminate hand compaction process. Which also considerably saves time with the rammers provided two stroke lengths, available, the compactor can be used for normal compaction / heavy compaction as well as C.B.R compaction. Specification :It is a motor driven mechanical compactor useful for soil compaction into 100mm or 150mm diameter moulds. Two sets of rammers are provided, one of 2.6 kg and arranged for 310mm drop and other 4.89kg and arranged for 450mm drop. For compaction soil into 150mm dia moulds, 100mm face dia rammers having weight 2.6kg and 4.89kg are used. Where as for 100mm dia moulds they are of 50mm dia. The rammer assembly is provided with a ratchet and pawl arrangement to lift it from the top of the soil layer.When the rammer reaches the required height the pawl release the rammer which falls freely on soil surface. The release mechanism is operated by an arm moving up and down which is connected to a reduction gear coupled to the motor through another arm. An automatic blow counter fitted to the compactor is used to set the number of blows. The base plate of the specimen mould is to be fitted to the rotating base plate of the instrument which marks 1/5 revolution per stroke. The equipment is suitable for operation on 230 Volts, 50 cycles, Single Phase, A.C. Supply moulds are to be ordered separately.

Unconfined Compression Test Apparatus.

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 a 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 apparatus consists of following: Load Frame 50kN capacity Electrically cum Manually Operated with 3 rates of strains 1.25mm, 1.50mm, 2.50mm/min 1No.Split Mould 38mm dia 1No.Set of Conning Tools 1 Set of Conning Plates with Springs 1 Set Proving Ring, 2.5kN capacity fitted with dial gauge with set of loading pads and calibration certificate by NCCBM (Govt Testing Lab) in a nice wooden carrying case Dial gauge 0.01mm x 25mm travel The Machine is fitted with HP Motor Suitable for Operation on 220V, Single Phase, 50Hz, AC Supply. civil lab equipments manufacturer
