The U-Box is a reliable and essential laboratory apparatus designed to evaluate the flowability, passing ability, and workability of Self-Compacting Concrete (SCC). This user-friendly instrument helps engineers, researchers, and quality control professionals determine how easily concrete flows through reinforcing bars without segregation. With its precise design and durable construction, the U-Box ensures consistent and accurate test results for SCC mix development and field quality assessment.

Crafted from high-quality, corrosion-resistant materials, the U-Box features two chambers separated by a vertically movable gate, allowing the concrete to pass and settle naturally. By measuring the height difference between the chambers, users can quickly assess the SCC’s ability to pass through obstacles—critical for ensuring high-performance concrete in modern construction projects.
