SOIL TESTING EQUIPMENT

Soil compaction is a fundamental requirement for the construction of earth fill for dams, reservoirs, canal embankments, highways, railways and runways.

This Apparatus is used for determination of the dry density of compact, fine, medium grained soils and for layers not exceeding 50 cm thickness.

Using a speedy moisture meter, the moisture content of soils, sand and other fine-grained material can be obtained quickly with reasonable accuracy.

This is used for determination of in situ dry density of natural or compacted fine grained soil, free from aggregates.

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.

• ~ 20cm Dia Brass Frame Sieves
• ~ 30cm Dia G.I. Frame Sieves
• ~ 45cm Dia G.I. Frame Sieves

This is a light, portable but sturdy sieve shaker suitable for bench mounting the side to side movement to the carrier which can take upto 7 sieves of 200mm dia is through a train of gears operated by a hand wheel.

The sieve table does not rotate but is inclined from the vertical axis and the direction on inclination charges progressively in clockwise direction. Carries upto 7 sieves of 150mm or 200mm diameter.

Moisture contents at which soil has smallest plasticity is called limit. For determination purpose plastic limit is defined as the water content at which a soil will just begin to crumble when rolled in to a thread of 3mm dia.

Shrinkage limit is the maximum water content at which a reduction in water content does not cause an appreciable reduction in volume of the Soil Mass.

Casagrande method in mechanical form is known as liquid limit method and has been in use for soil mechanics for a number of decades. This data of soils is useful to correlate mechanical properties of soil.

For determining the liquid limit of soils. This is specially useful to obtain reliable and accurate results of those soil which have low plasticity index.

This is for mechanical analysis and also other laboratory applications for stirring Speed approximately 4000 R.P.M. under load. For operation on 230V A.C. supplied with dispersion cup or baffle cup.

Consolidation of clay deposits leads to distress in buildings such as cracks and failures. Consolidation is the reduction of volume of soil due to expulsion of water from its pore space caused by sustained loading.

It is subjected to a constant normal load while an increasing horizontal force is applied to one of the sections of the shear box.

Used to determine the relevant proportions of clay-like or Plastic fines and dust in granular soils & fine aggregate

The apparatus is used for the laboratory determination of permeability of soil using a constant or a variable head.

The equipment is used for the determination of the relative density of cohesion less free draining soils and meets the essential requirements.

The extractor frame is used for taking out soil samples compacted or undisturbed, from 100mm dia and 150mm dia cylinders such as Core Cutters, Proctor moulds, C.B.R. moulds etc.

Designed to extract specimens from almost every type of sampling tube and mould used in solid engineering laboratory or in the field.

Augers are used to collect disturbed soil samples at reasonal depths for laboratory tests. Augers are available in two types and each in different sizes.
