L Shape Box AZA 1112 – SCC Passing Ability Test

L SHAPE BOX APPARATUS AZA1112

AZA1112 L Shape Box Apparatus is a precision testing device designed to evaluate the passing ability and flow performance of Self-Compacting Concrete (SCC) in congested reinforcement conditions. This apparatus simulates real-world scenarios such as densely reinforced beams, columns, tunnels, and bridge segments, where concrete must flow freely without segregation or blockage.

The distinctive L-shaped design creates a controlled flow path where freshly mixed SCC moves from a vertical chamber into a horizontal channel containing reinforcement bars. By measuring the concrete heights at both ends (H1 and H2), the H2/H1 ratio is calculated, providing a direct, quantitative assessment of the concrete’s ability to pass through obstructions.

Manufactured from durable, corrosion-resistant steel, AZA1112 is built for long-term laboratory and site use. It conforms to EN 12350-10 and EFNARC guidelines, ensuring global acceptance of test results.
