Description

Operating Principle

  1. Press the loading piston vertically into a freshly exposed soil surface.
  2. The engraved barrel scale displays the applied pressure directly in kg/cm².
  3. A sliding maximum load indicator ring retains the peak reading achieved.
  4. The measured value is used to estimate UCS or corresponding shear strength.

This simple, mechanical method provides instant results and is widely accepted for preliminary and comparative field evaluations.

LINEAR SHRINKAGE MOULD AZA0850

The AZA0850 Precision Linear Shrinkage Mould from AZALAB is a compact and highly accurate laboratory instrument designed for determining the linear shrinkage of fine-grained cohesive soils in accordance with BS 1377-2. This test is a key component of soil classification and is especially important in identifying shrink–swell behavior of clays and expansive soils.

Linear shrinkage testing measures the reduction in length of a soil specimen upon drying, expressed as a percentage of its original length. The results provide valuable insight into soil expansiveness, volume stability, and suitability for foundations, pavements, and earthworks.

Manufactured from high-quality brass or stainless steel, the AZA0850 mould offers precise internal dimensions, excellent corrosion resistance, and a smooth polished finish for easy sample preparation and removal. Its robust construction ensures repeatable, reliable results even under high-frequency laboratory use.

MOTORISED SAND EQUIVALENT SHAKER AZA0861

The AZA0861 Motorised Sand Equivalent Shaker is a precision-engineered laboratory instrument designed to automate the agitation phase of the Sand Equivalent Test. It ensures uniform, repeatable shaking in full compliance with ASTM D2419, AASHTO T176, and IS 2720 (Part 37), eliminating operator variability associated with manual shaking. This shaker is an essential accessory for soil, aggregate, and construction material testing laboratories where accurate assessment of sand cleanliness and clay-like fines is critical.
Purpose & Function The Sand Equivalent Test evaluates the relative proportion of sand versus clay-sized or plastic fines in fine aggregates. During testing, the sample and calcium chloride solution must be agitated for a defined stroke length and rate. The AZA0861 automates this process using a controlled reciprocating motion, delivering consistent agitation that improves repeatability, reduces operator fatigue, and enhances overall test reliability.

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.

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

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
