Liquid Limit Apparatus
The liquid limit, defined as the moisture content at which the soil passes from the plastic state to the liquid state, is very helpful in the classification of the potential properties of the soil material. The liquid limit gives a measure of the shearing resistance which a soil has when mixed with water. Casagrande Method or Cone Penetrometer Method can determine the liquid limit of soil.

Meets: - BIS 2720

N-tech Instruments offers the following models

Proctor Compaction Apparatus
N-tech Instruments
Proctor Compaction Apparatus
Compaction : Soil compaction is a fundamental requirement for the construction of earth fill for dams, reservoirs, canal embankments, highways, railways and runways. The relationship between soil moisture content and compacted dry density is very useful for deciding construction specifications and quality control of compacted earth fill. While designing an earth or earth retaining structure, the strength and deformation behaviour of soil is evaluated by testing soil specimen compacted to the density as would be achieved during construction. The construction quality control is essentially to check the density of compacted soil achieved in the field, thereby checking its strength.
Meets: - IS: 2720 (Part 7)-1987, IS: 2720 (Part 8)-1990, IS: 9198- 1979, IS: 10074-1982, BS: 1377
We offer two types of modals as follows .

N-tech Instruments
Consolidation single cell
Consolidation test is un-dimensional test considered extremely important in soil mechanics. Sample taken from adjacent areas of a single site show differential settlement even when tested using same techniques. Soil of similar strength may show varying consolidation. Samples are very carefully prepared and vertical settlement of the specimen in saturated or drained conditions carefully recorded when known load is applied.
Meets: - IS: 2720 (Part 15) 1986, IS: 12287-1988, BS: 1377, ASTM D2435
Consolidation Apparatus
The standard outfit comprises fixed ring type of consolidometer cell for testing specimens 60 mm dia x 20 mm thick, but the unit is so designed that specimens of varying sizes from 50 mm dia to 100 mm dia can also be tested. Besides, the same loading unit can be used with floating ring consolidometer cells, which can be supplied at extra cost. The standard outfit is supplied with a set of weights to give a total pressure of 10 kg/cm2 (besides a seating load of 0.05 kg/cm3 on the specimen), but an additional set of weights are required to reach the full capacity of 20 kg/cm2. The necessary accessories to perform the permeability test of the 'Varying Head' type can also be provided at extra cost. The outfit is also available as three-gang or six-gang in which three/six consolidometers are mounted on a single frame. The consolidation may be measured by the conventional dial gauges or using the transducers and electronic readout unit in Digital Modals.

Dynamic Cone Penetrometer
For determining the resistance of different soil strata to dynamic penetration of a 50 mm cone and thereby obtain an indication regarding their relative strengths or density or both. The method helps survey of large area in a short time. In some cases, especially if the depth is great, it may be difficult to pull out the cone after the completion of the test. Hence the cone without threads should be used in the case of deep soundings as it may be left in the ground. For shallow depths, generally up to 15 m, if the conditions permit, the cone with threads may be used. It consists of following:
