AUTOMATIC SOIL COMPACTOR AZA0867
The AZA0867 Automatic Soil Compactor from Azalab is a precision-engineered laboratory machine designed to perform Standard Proctor and Modified Proctor compaction tests with high repeatability and minimal operator dependency. The system mechanizes the hammer lifting and dropping process, ensuring consistent compaction energy in strict accordance with international standards.
This apparatus is essential for geotechnical laboratories involved in road construction, airfield pavements, embankments, earth dams, and foundation engineering, where accurate determination of Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) is critical for quality control and design validation.
Description
Principle of Operation
The AZA0867 operates using an electrically driven lifting mechanism that raises the compaction hammer to a predefined height and releases it to free-fall onto the soil sample contained in a standard compaction mould. A pre-settable automatic blow counter tracks each hammer drop and stops the machine once the specified number of blows per layer is achieved.
Automatic mould rotation ensures uniform distribution of compactive effort across the specimen surface, eliminating localized densification and improving test reliability.
Key Advantages
- High Reproducibility – Uniform hammer weight, drop height, and blow count ensure consistent compaction energy

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
