Description

Purpose of Test

The Aggregate Crushing Value (ACV) test determines the resistance of aggregate material to crushing under gradually applied compressive load. This is critical to ensure that aggregates used in:

  • Road pavements

  • Airport runways

  • Concrete structures

  • Railway ballast

can withstand heavy traffic loads and environmental stress.

A lower ACV percentage indicates stronger, more durable aggregates.

Working Principle

A known weight of dry aggregate is placed into a steel cylindrical mold and compacted using a tamping rod. A plunger is then inserted, and the assembly is placed in a compression testing machine where a load (typically up to 40 tons) is applied.

After loading, the crushed material is sieved through a 2.36 mm sieve, and the percentage of fines is calculated using:

ACV (%) = (Weight of fines / Original sample weight) × 100

Included Components

  • Steel Cylinder (150 mm internal diameter × 130 mm height)

  • Precision Steel Plunger (148 mm diameter)

  • Rigid Base Plate

  • Standard Tamping Rod (16 mm Ø × 600 mm length)

  • Metal Measure

Note: Compression testing machine is supplied separately.

Applications

  • Highway and road material quality control

  • Concrete and construction aggregate testing

  • Railway ballast strength evaluation

  • Civil engineering research and teaching

  • Government and private testing laboratories
