RELATIVE DENSITY TEST AZA0886

The AZA0886 Relative Density Test Apparatus from Azalab is a precision-engineered geotechnical testing system designed to determine the relative density (density index) of cohesionless, free-draining soils such as sands and gravels. Relative density is a critical parameter for evaluating the compactness, load-bearing behavior, and liquefaction susceptibility of granular soils.

Unlike cohesive soils, granular soils do not respond effectively to impact compaction methods. The AZA0886 utilizes a controlled vibratory table system to accurately establish both the maximum and minimum index densities, enabling reliable calculation of relative density in accordance with international standards.

Standards Compliance

  • IS 2720 (Part XIV)
  • ASTM D 4253 – Maximum Index Density

Test Principle (Summary)

  1. Soil is placed in the mould in its loosest state to determine minimum density.

  2. Soil is vibrated under surcharge using the vibratory table to achieve maximum density.

  3. Relative density is calculated using the measured dry densities or void ratios.

This method provides accurate characterization of soils that cannot be evaluated using conventional Proctor compaction tests.

LIQUID LIMIT DEVICE WITH COUNTER AZA0853

The AZA0853 Liquid Limit Device with Counter from AZALAB is a precision-engineered instrument used for determining the liquid limit of soils in accordance with the Casagrande method. This test is a fundamental component of soil classification and geotechnical investigation, providing critical insight into the plasticity, compressibility, and shear strength of fine-grained soils.

Designed for reliable, repeatable, and standardized testing, the AZA0853 is widely used in geotechnical laboratories, civil engineering departments, construction quality control labs, and academic institutions.

Principle of Liquid Limit Test (Casagrande Method)

The liquid limit is defined as the water content at which soil transitions from a plastic state to a liquid state. In practice, it is determined as the moisture content at which a standard groove cut in the soil sample closes over a length of 12.5 mm under 25 blows of the liquid limit apparatus.

The AZA0853 consists of a polished brass cup mounted on an adjustable bracket. The cup is repeatedly raised and dropped from a fixed height of 1 cm onto a hard rubber base by means of a manually operated cam mechanism. A built-in mechanical counter accurately records the number of blows, ensuring compliance with testing standards and reducing operator error.

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.

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.
