Description

Purpose & Test Principle

The AZA0882 operates on the core cutter method, where a cylindrical steel cutter is driven vertically into compacted soil to extract an undisturbed soil core of known volume. The recovered sample is trimmed flush, weighed, and tested for moisture content. Using these measurements, bulk density and dry density are calculated accurately.

This method is particularly effective for cohesive and fine-grained soils and is not recommended for gravelly or highly sandy materials.

PLASTIC LIMIT SET AZA0848

The AZA0848 Plastic Limit Set is a standardized soil testing kit designed for the accurate determination of the plastic limit of fine-grained soils, in accordance with IS: 2720 (Part 5) and ASTM D4318. The plastic limit is a fundamental soil index property used in soil classification and in evaluating soil behavior under varying moisture conditions. This test kit is an essential component of geotechnical investigations, civil engineering projects, and soil mechanics laboratories, providing reliable and repeatable results in both laboratory and field environments. Purpose & Importance The plastic limit represents the lowest moisture content at which soil remains plastic and can be rolled into threads of 3 mm diameter without crumbling. Determination of this limit is critical for:
  • Soil classification (Atterberg limits)
  • Assessing workability and consistency
  • Evaluating shrink–swell characteristics
  • Supporting foundation, pavement, and earthwork design

PLUMMET BALANCE AZA0862

The AZA0862 Plummet Balance is a specialized laboratory apparatus designed for determining the specific gravity of fine-grained soils, particularly clays and silts that are difficult to test using conventional pycnometer methods. It is widely used in geotechnical engineering, soil mechanics laboratories, and construction quality control applications. Manufactured by Azalab, the instrument complies with ASTM D854 and IS 2720 (Part 3 / Sec 1) standards and provides rapid, repeatable, and reliable results for dispersed soil samples commonly used in sedimentation, pipette, and hydrometer analyses.
Working Principle The plummet balance method determines the specific gravity of soil solids by measuring the apparent weight of a suspended plummet immersed in a soil–water suspension. The balance pointer directly indicates the percentage of soil in suspension via a calibrated scale, eliminating lengthy calculations. A rack-and-pinion height adjustment allows the plummet to be positioned at the required depth. The percentage of soil in suspension is read directly from the graduated scale, making this method faster and more user-friendly than traditional sedimentation calculations. The set is supplied with a temperature correction chart relating the constant K to suspension temperature for soils with specific gravity ranging from 2.4 to 2.8, facilitating accurate application of Stokes’ law.

SEMI AUTOMATIC CONE PENETROMETER AZA0852

The AZA0852 Semi Automatic Cone Penetrometer from AZALAB is a precision-engineered laboratory instrument used for determining the liquid limit and consistency characteristics of fine-grained soils. Designed to eliminate operator-dependent errors, this semi-automatic model ensures uniform cone release and repeatable penetration results, making it an ideal choice for geotechnical, civil engineering, and construction material testing laboratories. The apparatus conforms to IS 2720 (Part 5) and BS 1377 standards and is widely used for soil classification, foundation assessment, and settlement analysis. Its semi-automatic clutch-based drop mechanism allows the cone to penetrate the soil sample under controlled conditions for a fixed duration of 5 seconds, ensuring consistent and reliable test outcomes.

Principle of Operation

A soil paste prepared at known moisture content is placed in the sample cup. The standardized cone, attached to a calibrated weight, is released using the semi-automatic clutch mechanism, allowing free fall penetration into the soil. After the specified time (typically 5 seconds), the penetration depth is measured using a high-precision dial gauge. The moisture content corresponding to a penetration of 20 mm is considered the liquid limit of the soil, as defined in IS and BS standards.

SHRINKAGE LIMIT SET AZA0849

The AZA0849 Shrinkage Limit Set from AZALAB is a precision-engineered laboratory instrument used for determining the shrinkage limit of cohesive soils, a critical parameter within the Atterberg limits framework. This test plays a vital role in understanding the volume change characteristics of fine-grained soils when subjected to drying. The shrinkage limit represents the maximum moisture content at which further reduction in water content does not cause any appreciable decrease in soil volume. Beyond this point, air begins to enter the soil voids, and the soil mass maintains a constant volume. Accurate determination of this parameter is essential for predicting soil behavior in foundations, embankments, earth dams, and pavement structures.

Standards Compliance

The AZA0849 Shrinkage Limit Set conforms to major national and international testing standards, ensuring reliable and universally accepted test results:
  • IS 2720 (Part VII)
  • ASTM D427
  • BS 1377
  • AASHTO T 92

SOIL CONE PENETROMETER AZA0851

The AZA0851 Precision Cone Penetrometer from AZALAB is a high-accuracy laboratory instrument designed for determining the liquid limit of fine-grained soils using the cone penetration method. The apparatus fully complies with IS 2720 (Part 5) and ASTM D4318, making it suitable for standardized soil classification and geotechnical investigations. Unlike the Casagrande method, the cone penetrometer provides a more objective and repeatable measurement of liquid limit by correlating soil consistency to the depth of penetration of a standardized cone under its own weight. This method is widely preferred in modern soil mechanics laboratories due to reduced operator dependency and higher precision.

Principle of Operation

A soil paste prepared at a known moisture content is placed in the sample cup. The stainless steel cone, of specified mass and angle, is allowed to penetrate the soil freely for 5 seconds. The depth of penetration (up to 20 mm) is measured using a precision depth gauge. The moisture content corresponding to 20 mm penetration is defined as the liquid limit of the soil.

Standards Compliance

  • IS 2720 (Part 5) – Determination of liquid and plastic limits
  • ASTM D4318 – Liquid Limit, Plastic Limit, and Plasticity Index of Soils
