Rammer
MI.SO-1001
Compaction Test Rammer, Manual
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.

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.

MI.SO-1006
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:

California Bearing Ratio
The CBR test is used for determining the relative bearing ratio and expansion characteristics under known surcharge weights of base, sub-base and sub grade soils for the design of roads, pavements and runways. Tests can be conducted on all types of soils including sand, gravel and washed stone (passing through 20 mm IS Sieve). The CBR test is used extensively in selection of materials and control of sub grades. The procedure consists of loading soil with a circular piston, 50 mm dia face and maintaining a penetration rate of 1.25 mm/min. The load is noted and the results of test on natural or recompacted soils, in soaked and unsoaked conditions, can be compared with standard test results.

MI.SO-1010
California Bearing Ratio Test Apparatus, Field Type
The use of the in-situ CBR apparatus on large road construction projects has increased considerably in recent years. This apparatus, mounted on a rolled steel joist cantilevered from the back of the truck or fitted to the underside of a mobile frame, can be used to determine the bearing capacity of soils quickly and efficiently. This method of testing in-situ, using piston penetration, is useful for determining the load carrying capacity in the field, when the in-place density and water contents are such that the degree of saturation is 80 % or greater, when the material is coarse grained and cohesion less so that it is not affected by changes in the water content and when the material has been in place.

Liquid Limit, Hand Operated
MI.SO-1012
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.
