Description

Working Principle

The AZA0930 operates on the dynamic plate load (impulse) testing principle:

  1. A rigid circular loading plate is placed on the prepared test surface.

  2. A standardized drop weight is lifted to a fixed height and released.

  3. The impact load is transferred through a spring system to the ground.

  4. A high-precision geophone measures peak surface deflection.

  5. An integrated load cell records applied force.

  6. The control unit calculates the Dynamic Deformation Modulus (Evd / E-value).

Multiple drops are performed at each test point to ensure repeatability and accuracy. Results are displayed within minutes.

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.

SHRINKAGE LIMIT SET AZA0849

The AZA0849 Shrinkage Limit Set from AZALAB is a precision-engineered laboratory instrument used for determining the shrinkage limit of cohesive soils, a critical parameter within the Atterberg limits framework. This test plays a vital role in understanding the volume change characteristics of fine-grained soils when subjected to drying. The shrinkage limit represents the maximum moisture content at which further reduction in water content does not cause any appreciable decrease in soil volume. Beyond this point, air begins to enter the soil voids, and the soil mass maintains a constant volume. Accurate determination of this parameter is essential for predicting soil behavior in foundations, embankments, earth dams, and pavement structures.

Standards Compliance

The AZA0849 Shrinkage Limit Set conforms to major national and international testing standards, ensuring reliable and universally accepted test results:
  • IS 2720 (Part VII)
  • ASTM D427
  • BS 1377
  • AASHTO T 92
