SEMI AUTOMATIC COMPRESSION TESTING MACHINE AZA1138
The Azalab AZA1138 Semi Automatic Compression Testing Machine is engineered for high-precision compressive strength testing of concrete cubes, cylinders, blocks, and pavers. Designed for construction quality control, laboratory testing, R&D, and compliance verification, this 2000 kN (200-ton) unit offers the perfect balance between automation and operator oversight.
Built to comply with ASTM C39, EN 12390-4, and IS 516, the AZA1138 ensures accurate, repeatable, and traceable strength measurements essential for modern infrastructure and structural design.
The machine features a motorized hydraulic power pack, automatic pace-rate control, and a digital load display with peak-hold functionality. This reduces operator dependency, minimizes human error, and increases throughput in busy laboratories. A heavy-duty four-column or C-frame structure ensures rigidity and minimal deflection under full load. All platens are precision-ground and hardened to ensure uniform stress distribution.
The semi-automatic system automatically regulates loading rate while allowing the operator to initiate and stop tests via a user-friendly control panel. Optional PC connectivity allows for data logging, reporting, and seamless integration into lab workflows.

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.
