Compaction Factor Apparatus

Product Code : MSI 2007

Product Description:

The Compaction Factor Apparatus is engineered to measure the workability and compaction dynamics of fresh concrete mixes, specifically targeting low-workability or dry-lean mixes that are unsuited for standard slump tests. Built in full alignment with IS: 1199 and BS 1881-103, this laboratory apparatus features a rigid structural steel frame supporting two calibrated, conical hoppers aligned perfectly over a lower cylindrical receiving measure. Each hopper is equipped with a quick-release, spring-loaded trapdoor mechanism, allowing the concrete mix to drop freely under standard gravitational forces to calculate precise density compaction ratios 

Applications

• Civil Engineering Laboratories

• Construction Quality Control

• Ready Mix Concrete (RMC) Plants

• Highway & Bridge Construction

• Dam & Infrastructure Projects

• Precast Concrete Industry

• Research & Development Laboratories

Working Principle

Fresh concrete is placed into the upper hopper and released through the quick-release trapdoor into the lower hopper, and then into the receiving cylinder. The weight of the partially compacted concrete is compared with the weight of fully compacted concrete to determine the Compaction Factor, which indicates the workability and consistency of the concrete mix.
