About 150x130 mm Aggregate Crushing Value Apparatus , Body material

The 150 130 mm Aggregate Crushing Value (ACV) Apparatus is a precision laboratory testing equipment used for determining the crushing strength or resistance of coarse aggregates under gradually applied compressive load. It is widely used in highway engineering laboratories and construction material testing facilities to assess the suitability of aggregates for road and concrete work.

Body Material:

The body of the Aggregate Crushing Value Apparatus is manufactured using heavy-duty mild steel (MS) / cast iron construction for high strength, rigidity, and long service life. All structural components are precision-machined to ensure accurate alignment during testing. The surfaces are typically powder-coated or anti-corrosive painted to protect against rust, moisture, and laboratory wear conditions.

The plunger, cylinder, and base plate are also made from hardened steel or cast iron, ensuring resistance to deformation under high compressive loads and maintaining test accuracy over repeated use.

Key Features:

• Heavy-duty MS / cast iron body construction
• Corrosion-resistant powder-coated finish
• Precision-machined cylindrical mould (150 130 mm)
• High load-bearing capacity and stability
• Durable plunger and base plate assembly
• Suitable for repeated laboratory use

Applications:

• Highway and road construction laboratories
• Civil engineering testing labs
• Aggregate quality control departments
• Infrastructure development projects
• Research and material testing institutions

Working Principle:

The apparatus measures the resistance of aggregates to crushing under a gradually applied compressive load. The percentage of crushed material indicates the aggregate crushing value, helping determine its strength and suitability for construction use.

Durable Construction for Reliable Testing

Built with heavy-duty cast iron and a hardened alloy steel plunger, this apparatus delivers exceptional durability and performance. Its powder-coated finish ensures resistance against corrosion even in challenging lab environments. The smooth, machined surfaces and fully painted body allow for easy cleaning and maintenance, prolonging service life and accuracy.


Precision and Compliance Assured

Engineered to meet stringent IS: 2386 (Part 4) and BS 812 standard requirements, this apparatus provides accurate measurements of aggregate crushing value between 0-100%. The removable base and precise plunger alignment ensure repeatable, consistent test results for aggregates sized 10 mm to 12.5 mm, supporting reliable construction quality control.


Manual Operation, No Power Needed

The apparatus operates entirely by mechanical hand action, requiring no electrical supply. This manual design not only enhances safety but also offers flexibility in any laboratory or field setting. Its uniform manual load application ensures trustworthy testing outcomes, whether table or floor-mounted.
