Polished Mechanical Steel Compaction Factor Apparatus

The Compaction Factor Apparatus is a laboratory testing instrument used to determine the workability of fresh concrete, particularly for mixes that are too dry or harsh for the slump test.
It operates on the principle of measuring the ratio of the weight of partially compacted concrete to fully compacted concrete, giving an accurate indication of the concrete’s workability.
The apparatus consists of two conical hoppers mounted above a cylindrical mould, equipped with quick-release traps that allow the concrete to fall freely from one hopper to another and into the mould.

• Suitable for low-workability concrete where slump test fails

• Provides quantitative measurement of workability through compaction factor

• Rugged and durable construction for repeated laboratory use

• Corrosion-resistant metal parts ensure long service life

• Portable and easy-to-operate design for field or lab testing

• Conforms to IS: 1199 – Methods of Sampling and Analysis of Concrete

• Used in construction quality control laboratories

• Suitable for research and educational institutions

• Ideal for testing dry or harsh concrete mixes

• Commonly employed in civil engineering and infrastructure testing
