CONSOLIDATION APPARATUS (THREE GANG MODEL) AZA0898

The AZA0898 Three Gang Consolidation Apparatus is a high-capacity geotechnical testing system designed to simultaneously evaluate the consolidation characteristics of three independent soil specimens. Engineered for efficiency and accuracy, this apparatus is ideal for laboratories handling large testing volumes or time-critical geotechnical investigations.

Used for one-dimensional consolidation (oedometer) testing, the AZA0898 enables precise determination of soil compressibility and settlement behavior under incremental static loading. By allowing three tests to run concurrently—each with independent loading control—the system significantly reduces testing time while maintaining high measurement accuracy.

Description

Purpose and Function

Soil consolidation testing is fundamental for predicting long-term settlement of foundations, embankments, pavements, and earth structures. The AZA0898 allows engineers to determine critical parameters such as:

  • Coefficient of consolidation (cᵥ)

  • Compression index (C𝑐)

  • Swelling index (C𝑠)

  • Preconsolidation pressure (p′𝑐)

The three-gang configuration provides maximum operational flexibility, enabling different loads, soil types, or test schedules to be run simultaneously.


Key Applications

  • Soil compressibility and settlement analysis

  • Foundation and embankment design studies

  • Pavement and infrastructure geotechnical evaluation

  • Academic research and commercial soil testing

  • Long-term consolidation and swelling behavior assessment


Construction & Features

Each AZA0898 Three Gang Consolidation Apparatus includes:

  • Rigid steel loading frame with minimal deflection

  • Three independent loading stations (gangs)

  • Dead-weight loading system with lever arms

  • Three standard consolidation cells (oedometer cells)

  • Mechanical dial gauges for deformation measurement

  • Precision-machined components for accurate load transfer

Optional configurations include electronic LVDTs, digital displays, and data acquisition systems for automated, high-resolution settlement monitoring.


Standards and Compliance

Designed to comply with major international soil testing standards:

  • ASTM D2435 / ASTM D3877 – One-Dimensional Consolidation

  • BS 1377 Part 5 – Compression and Swelling Tests

  • IS 2720 (Part 15) – Determination of Consolidation Properties

Frequently Asked Questions (FAQ)

Q1: What is the advantage of a three gang consolidation apparatus?
It allows three consolidation tests to be conducted simultaneously, greatly increasing laboratory efficiency and reducing total testing time.

Q2: Can different loads be applied to each specimen?
Yes. Each gang operates independently, allowing different loads and testing schedules.

Q3: What parameters can be determined using AZA0898?
Coefficient of consolidation (cᵥ), compression index (C𝑐), swelling index (C𝑠), and preconsolidation pressure (p′𝑐).

Q4: Can the system be automated?
Yes. The apparatus can be supplied with or upgraded to electronic LVDTs and data logging systems.

Q5: What specimen sizes are supported?
Standard consolidation cells of 50 mm, 63.5 mm, or 75 mm diameter are typically supported.
