Cast Iron Aggregate Impact Test Apparatus

About Cast Iron Aggregate Impact Test Apparatus

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.
