Cast Iron Aggregate Impact Test Apparatus

Cast Iron Aggregate Impact Test Apparatus About

The Cast Iron Aggregate Impact Test Apparatus is a precision laboratory equipment used for determining the impact value of coarse aggregates, which indicates their toughness and resistance to sudden shock or impact. It is widely used in highway engineering laboratories and construction material testing facilities to assess the suitability of aggregates for road construction and concrete works.

This apparatus is manufactured using high-quality cast iron, providing excellent strength, rigidity, and durability for repeated testing under heavy impact conditions. It consists of a robust base, cylindrical measure, hammer assembly, and other essential components designed as per standard specifications.

The machine delivers controlled impact blows on aggregate samples, and the resulting fines are measured to determine the aggregate impact value, ensuring accurate and reliable test results.

Key Features:

• Heavy-duty cast iron construction for long service life
• Rigid and stable base for accurate testing
• Precision-engineered hammer and guide assembly
• Corrosion-resistant finish
• Easy to operate and maintain
• Suitable for continuous laboratory use

Applications:

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

Working Principle:

The apparatus subjects aggregate samples to a series of controlled impact blows from a standard hammer. The percentage of fines produced after testing indicates the impact value, which reflects the toughness and durability of the aggregates.

Precision and Durability for Aggregate Testing

Designed for civil engineering laboratories, this apparatus features a high-grade cast iron base and body for maximum longevity and resistance to wear. The anti-corrosive powder coating and hardened steel hammer guide ensure reliable, repeatable test results under a variety of laboratory conditions. Its manual operation mode means no power supply is needed, making it a dependable choice in diverse environments.


Complies with International Standards

This apparatus strictly adheres to IS 2386 (Part 4):1963 and BS 812, ensuring it meets thorough international requirements for aggregate impact testing. With its standard cup diameter and calibrated hammer drop height, all measurements align precisely with industry best practices and codes, guaranteeing trustworthy results for every test.
