J-RING, NARROW GAP AZA1109

AZA1109 J-Ring – Narrow Gap is a precision testing apparatus designed to evaluate the passing ability of Self-Compacting Concrete (SCC) under highly restrictive conditions. This device simulates densely congested reinforcement zones by creating artificial obstructions that the fresh SCC must flow through without blocking or segregating. It is an essential tool for determining whether SCC mixes are suitable for heavily reinforced structural elements such as beams, columns, and shear walls.

The narrow gap design offers a more stringent test compared to standard J-Rings, allowing engineers and quality control professionals to accurately observe flow diameter, T50 flow time, and blocking behavior. When used in combination with a standard slump flow cone, AZA1109 provides reliable, repeatable results that help optimize mix designs and ensure consistent on-site performance.

Manufactured from durable, corrosion-resistant steel, the AZA1109 is built for repeated use in laboratory and field testing environments. The apparatus is fully compliant with ASTM C1621 and EFNARC guidelines, ensuring internationally accepted testing procedures.
