Sand Replacement Method
Sand Pouring Cylinder Apparatus, IS: 2720 (Part 28)

This Apparatus is used for determination of the dry density of compact, fine, medium grained soils and for layers not exceeding 50 cm thickness. A circular hole is dug into the ground, all the soil from within it collected, weighed and dried, and the hole back-filled with a standard uniform sand or fine gravel, poured from a calibrated container for calculating the volume of hole. The apparatus consists of the following:

Sensitive Volume Change Gauge

The Volume Change Gauge illustrated works on the principle of reversing the direction of flow when the limit of the volume change scale is reached. The number of cycles with the volume of fluid handled in each cycle provides the total volume change, whereas the sensitivity is governed by the dia of the polythene tube used.

The sensitive volume change gauge has realized sensitivity of 0.003 ml/mm with the 6 ml volume of fluid per cycle. The apparatus consists of a volume measuring polythene tube running along both sides of a scale and connected at both ends to two mercury traps. These traps are connected to flow reversal valves through a manifold. The length of the polythene tube is enough to measure 6 ml volume of fluid per cycle. A small pallet of mercury is introduced in the circuit to be used as a cursor, and the movement of pallet is measured. The unit is tested to a pressure of 20bar (20 kg/cm2) and is designed for wall mounting.

Shrinkage Limit

IS:2720 (Part 7), 10077, ASTM D 427, BS:1377, AASHO T 92
The Shrinkage Limit of a soil is defined as the moisture content at which any further reduction of moisture will not cause volume reduction. The shrinkage of clayey soil can be very significant. A fully saturated soil specimen is allowed to dry in free air and its volume is measured repeatedly by immersing in a mercury bath. From the data obtained from this test, Shrinkage Limit, Shrinkage Ratio, Shrinkage Index and Volumetric Shrinkage can be calculated. The choice of puddle clay materials is often governed by the results obtained from this test.

Particle Size Analysis

The analysis of soils by particle size provides a useful engineering classification system from which a considerable amount of empirical data can be obtained. This helps in ascertaining possible frost action, determining graded filters, selection of grouting materials, designing of cement and asphaltic concrete mixes, etc. Two different procedures are used for coarse and fine soils. Sieving is used for gravel as well as sand size particles and sedimentation procedures are used for finer soils.

For soils containing coarse and fine soil particles, it is usual to employ both sieving and sedimentation procedures. ILE provides the following range of equipment for performing particle size analysis.

Sieve Shaker

To make the process of sieving easier and quicker, electrically operated mechanical Sieve Shakers are offered for dry sieving. These Sieve Shakers are popularly used not only in soil laboratories but also in a number of industries where sieving is required; such as for ores, refractory materials, minor aggregates, pigments, powdered coal, soap, cement, roofing materials, plastic moulding powders and pharmaceuticals. The Sieve Shaker can carry up to 7 sieves.

Moisture Content
IS: 2720 (Part 2); BS: 1377, 1924 and ASTM D2216

Moisture content of soil is generally measured as a ratio of the weight of water to the weight of solids, expressed as a percentage. As soil behaviour depends on its moisture content, it is one of the basic parameters defining the soil condition. To a control engineer, even a rapid moisture content check is extremely useful, as it gives an indication of the existing characteristics of the soil, which enables him some extent to decide on the pattern of test programme. A number of procedures have been suggested for carrying out water content tests in IS : 2720 (Part 2); BS : 1377, 1924 and ASTM D2216. The equipment listed below gives a range of suitable apparatus for this purpose.

Infra-Red Moisture MeterIS: 2720 (Part 2) - 1973
This moisture meter has been designed for rapid and accurate determination of the moisture content of a wide variety of materials. It is a torsion wire instrument, the torque being applied to one end of the wire by means of a calibrated drum to balance the loss of weight as the test sample dries under infrared radiation. The speed of drying (about 30 min) thus obtained combined with the frictionless balancing system gives the results as accurate as those obtained by standard oven drying method. Since drying and weighing are simultaneous, it is specially useful for determination of moisture in substance, that quickly reabsorbs moisture after drying.

The infrared radiation is controlled by a voltage regulator and thereby provides excellent heat control. The instrument is provided with an indicator lamp. The torsion balance has a built-in magnetic damper to reduce pan vibrations enabling quicker weighing. The balance scale (drum) is divided in terms of moisture percentages on wet weight basis, which are read directly from it. Graduations are from 0 to 100% in 0.2 % divisions, but readings may be estimated to 0.1 % moisture content. It is a portable unit, supplied complete with one Infra-Red Lamp and Thermometer. Suitable for operation on 230 V, 50 Hz, Single phase, AC Supply.

Capacity : 5 g approx.
Sensitivity : 10 mg approx.
Range : 0 to 100 % moisture content on wet weight basis
Reading accuracy : ± 0.25%
Probable error compared to oven methods : ±0.25 % in the lower ranges up to 25 % ±1 % for moisture contents above 50 %
