STANDARD COMPACTION TEST AZA0864

The AZA0864 Standard Compaction Test Apparatus from Azalab is precision-engineered to perform the British Standard Proctor (Light Compaction) Test, as specified in BS 1377-4 and BS 1924-2. This apparatus is used to determine the Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of soils subjected to light compactive effort.

The test simulates field compaction achieved by light rollers and rammers and is essential for quality control of subgrades, embankments, road bases, and foundation soils. The AZA0864 is widely used in geotechnical laboratories, site investigation works, and academic institutions following British Standards.

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
