HEAVY COMPACTION TEST AZA0865

The AZA0865 Heavy Compaction Test Apparatus from Azalab is designed for performing the Heavy Compaction Test, commonly known as the Modified Proctor Compaction Test. This test establishes the relationship between moisture content and dry density of soils under high compaction energy, simulating field conditions achieved by modern heavy compaction equipment. The apparatus is essential for determining Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) for soils used in heavy-duty pavements, airfield runways, embankments, dams, and foundations, where higher strength and durability are required.
Purpose of Test The Modified Proctor Test applies significantly greater compactive effort compared to the Standard Proctor test. The results are used by engineers to:
    • Specify target field compaction densities
    • Control moisture during earthwork
    • Ensure long-term stability and load-bearing performance

PARTICLE SIZE SEDIMENTATION (HYDROMETER METHOD) AZA0857

AZA0857 – Particle Size Sedimentation Apparatus (Hydrometer Method) The AZA0857 Particle Size Sedimentation Apparatus (Hydrometer Method) from AZA Lab is designed for determining the particle size distribution of fine-grained soils, particularly silts and clays smaller than 75 microns. This method is widely adopted in soil mechanics, geotechnical engineering, civil construction quality control, and academic laboratories where accurate characterization of cohesive soils is essential. The hydrometer method is based on the sedimentation principle governed by Stokes’ Law, measuring changes in the density of a soil–water suspension over time. By recording hydrometer readings at defined intervals, the percentage of soil particles remaining in suspension is calculated, enabling precise determination of grain size distribution for fine soils beyond the practical limits of sieve analysis.

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

STANDARD COMPACTION TEST AZA0863

The AZA0863 Standard Compaction Test Apparatus from Azalab is designed to perform the Standard Proctor Compaction Test, a fundamental geotechnical laboratory procedure used to determine the Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of soils. These parameters are essential for ensuring proper soil compaction in the construction of roads, embankments, foundations, and other earth structures. This apparatus simulates light compaction effort typically applied in the field and provides reliable, repeatable results for laboratory quality control and design verification.
Purpose & Principle The Standard Compaction Test establishes the relationship between soil moisture content and dry density under a standard compactive effort. Soil samples are compacted in layers within a cylindrical mould using a specified hammer weight and drop height. By testing at varying moisture contents and plotting a compaction curve, the MDD and OMC are obtained.
