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.

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.

The AZA0902 Motorised Unconfined Compression Tester from Azalab is a fundamental geotechnical testing instrument designed for accurate determination of the unconfined compressive strength (qᵤ) of cohesive soils. This parameter is critical for evaluating the undrained shear strength of clays and silts and is widely used in foundation design, slope stability assessment, and preliminary geotechnical investigations.

Unlike manual systems, the motorised operation of the AZA0902 ensures a constant and controlled rate of strain, which is essential for achieving repeatable and standards-compliant test results. The apparatus is designed in accordance with internationally recognized standards such as ASTM D2166 and IS 2720 (Part 10).

The AZA0891 Universal Hydraulic Extruder from Azalab is a critical laboratory apparatus engineered for the controlled and disturbance-free extrusion of undisturbed soil samples from sampling tubes. Accurate evaluation of in-situ soil properties—such as shear strength, compressibility, and permeability—depends heavily on maintaining the natural structure of soil specimens during preparation. The AZA0891 is specifically designed to meet this requirement with precision and reliability.

Powered by a smooth hydraulic extrusion system and housed in a robust ZI 3045 heavy-duty steel frame, this extruder ensures uniform, continuous pressure during sample removal. This eliminates the jerks and uneven forces common in manual or screw-type extruders, significantly reducing the risk of cracking, distortion, or structural alteration of sensitive soil samples.

The AZA0906 Volume Change Gauge is a high-precision laboratory instrument designed to accurately measure volume change in saturated soil specimens during triaxial shear, consolidation, and permeability tests. It is a critical component of a complete triaxial testing system, enabling precise determination of volumetric strain, drainage behavior, and effective stress parameters.

The AZA0906 is particularly essential for Consolidated Undrained (CU) and Consolidated Drained (CD) triaxial tests, where monitoring the inflow or outflow of water from the specimen is fundamental to understanding soil compression, dilation, and pore pressure response.

The AZA0871 Water Level Indicator from Azalab is a high-precision electronic instrument designed for accurate measurement of groundwater levels in boreholes, wells, standpipes, and observation tubes. It is an essential tool for professionals involved in groundwater monitoring, environmental site assessments, hydrological investigations, geotechnical projects, and dewatering operations.

Accurate water level measurement is fundamental for understanding aquifer behavior, monitoring seasonal or pumping-induced fluctuations, assessing contamination plumes, and supporting the design of foundations, irrigation systems, and water resource management plans. The AZA0871 provides a reliable, fast, and field-ready solution for both static and dynamic water level measurements.
