Description

Description

Principle of Operation

The AZA0908 operates by transmitting controlled air pressure to water inside a sealed pressure chamber. This water applies uniform lateral pressure around the triaxial cell, which in turn confines the soil specimen enclosed in a rubber membrane. A calibrated pressure gauge allows continuous monitoring and adjustment of the applied pressure throughout the test.

The system is designed for routine laboratory testing where stable confining pressure up to 10 kg/cm² (≈1000 kPa) is required.

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.

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.

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.

SAND EQUIVALENT TEST SET AZA0859

The AZA0859 Sand Equivalent Test Set from AZA Lab is a standardized laboratory and field testing apparatus used to determine the relative proportion of sand versus clay-like or plastic fines in fine aggregates and granular soils. This test is critical in construction quality control where aggregate cleanliness directly affects the performance of asphalt pavements, concrete mixes, and base course layers. The test set conforms to ASTM D2419, IS 2720 (Part 37), and AASHTO T176, ensuring accurate, repeatable, and specification-compliant results. The Sand Equivalent Value (SEV) provides a simple numerical indication of aggregate quality by comparing the height of settled sand to the height of clay suspension after sedimentation.
Working Principle A prepared fine aggregate sample is placed in a graduated cylinder and mixed with a standard calcium chloride-based solution. After agitation and a controlled settling period, heavier sand particles settle at the bottom while lighter clay and silt particles remain in suspension. The Sand Equivalent Value (SEV) is calculated as: SEV = (Height of Sand / Height of Clay Suspension) × 100 Higher SEV values indicate cleaner aggregates with lower clay contamination, which are preferred for structural and pavement applications.

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.
