LATERAL PRESSURE ASSEMBLY 10KG / cm² AZA0908
The AZA0908 Lateral Pressure Assembly (10 kg/cm²) from Azalab is a critical geotechnical laboratory accessory designed to apply and maintain uniform lateral (confining) pressure on soil specimens during triaxial shear and related tests. By accurately simulating in-situ stress conditions, this assembly ensures reliable determination of soil shear strength, deformation characteristics, and effective stress parameters.
The unit is primarily used with standard triaxial cells for UU, CU, and CD triaxial compression tests, making it indispensable for foundation design, slope stability analysis, and advanced soil research
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.

DYNAMIC CONE PENETROMETER AZA0872
The AZA0872 Dynamic Cone Penetrometer (DCP) from Azalab is a robust, field-proven instrument designed for rapid in-situ evaluation of soil strength, stiffness, and compaction. It is extensively used by civil engineers, geotechnical consultants, and construction teams for pavement design, quality control, and site investigation works.
The DCP test provides a fast and economical method to assess the strength of subgrades, sub-bases, and granular base course layers, with results that can be directly correlated to California Bearing Ratio (CBR) values. This eliminates the need for time-consuming laboratory testing or undisturbed soil sampling, enabling immediate decision-making at site.

LIQUID LIMIT DEVICE WITH COUNTER AZA0853
The AZA0853 Liquid Limit Device with Counter from AZALAB is a precision-engineered instrument used for determining the liquid limit of soils in accordance with the Casagrande method. This test is a fundamental component of soil classification and geotechnical investigation, providing critical insight into the plasticity, compressibility, and shear strength of fine-grained soils.
Designed for reliable, repeatable, and standardized testing, the AZA0853 is widely used in geotechnical laboratories, civil engineering departments, construction quality control labs, and academic institutions.
Principle of Liquid Limit Test (Casagrande Method)
The liquid limit is defined as the water content at which soil transitions from a plastic state to a liquid state. In practice, it is determined as the moisture content at which a standard groove cut in the soil sample closes over a length of 12.5 mm under 25 blows of the liquid limit apparatus.
The AZA0853 consists of a polished brass cup mounted on an adjustable bracket. The cup is repeatedly raised and dropped from a fixed height of 1 cm onto a hard rubber base by means of a manually operated cam mechanism. A built-in mechanical counter accurately records the number of blows, ensuring compliance with testing standards and reducing operator error.

SOIL CONE PENETROMETER AZA0851
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
