HEAVY COMPACTION TEST AZA0865

The AZA0865 Heavy Compaction Test Apparatus from Azalab is designed for performing the Heavy Compaction Test, commonly known as the Modified Proctor Compaction Test. This test establishes the relationship between moisture content and dry density of soils under high compaction energy, simulating field conditions achieved by modern heavy compaction equipment. The apparatus is essential for determining Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) for soils used in heavy-duty pavements, airfield runways, embankments, dams, and foundations, where higher strength and durability are required.
Purpose of Test The Modified Proctor Test applies significantly greater compactive effort compared to the Standard Proctor test. The results are used by engineers to:
    • Specify target field compaction densities
    • Control moisture during earthwork
    • Ensure long-term stability and load-bearing performance

METHYLENE BLUE TEST SET AZA0860

The AZA0860 Methylene Blue Test Set from AZA Lab is a comprehensive laboratory system designed to determine the clay content and clay activity in fine aggregates and soils through measurement of the Methylene Blue Value (MBV). The test is highly sensitive to active clay minerals—particularly montmorillonite—that can adversely affect the performance of concrete, asphalt, and other construction materials. This method is widely adopted in aggregate quality control, concrete mix design, asphalt technology, and geotechnical investigations, providing a reliable indicator of fines reactivity and cation exchange capacity.
Standards Compliance
  • EN 933-9 – Tests for geometrical properties of aggregates (Methylene Blue Test)
  • NF P94-068
  • UNE 83 180
  • UNI 8520-15
  • ASTM C837 – Methylene Blue Index of Clay in Fine Aggregate

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.
