AGGREGATE CRUSHING VALUE APPARATUS AZA0982
The AZA0982 Aggregate Crushing Value (ACV) Apparatus is a heavy-duty laboratory testing system used to determine the crushing strength of coarse aggregates. It is designed for standard compliance testing required in road construction, concrete production, and civil engineering quality control.
Manufactured with precision-machined components, this apparatus delivers consistent, accurate, and repeatable results in accordance with IS:2386 (Part IV) and BS 812 standards.
Key Features
- Measures crushing strength of coarse aggregates
- Conforms to IS:2386 (Part IV) and BS 812 standards
- Precision-machined steel cylinder and plunger
- Heavy-duty, corrosion-resistant construction
- Supplied with complete accessories for immediate testing
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
