ELECTRONIC CONCRETE TEST HAMMER (SCHMIDT HAMMER) AZA1149

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.

The AZA1125 One-Piece Plastic Cube Mould (150 mm) from Azalab is a next-generation alternative to traditional metal cube moulds. Built from high-strength, non-deformable engineering plastic, this mould is designed to offer superior ease of use, long service life, and consistent dimensional accuracy for concrete compressive strength testing.

Its seamless, single-piece construction eliminates the need for bolts, screws, or external frames. Users simply apply demoulding oil, cast the concrete, and after curing, eject the cube using compressed air or water pressure, achieving clean and damage-free removal every time.

Compared to heavy metal moulds, the AZA1125 weighs nearly 90% less, providing clear advantages in portability, handling, and storage—making it ideal for both laboratory and on-site testing environments. Manufactured using an eco-friendly, non-polluting process, this mould supports sustainability goals in modern construction testing.

AZA1111 V Funnel is a precision laboratory apparatus designed to measure the flow time and viscosity of Self-Compacting Concrete (SCC). It evaluates how quickly fresh SCC passes through a narrow, V-shaped section under the action of gravity, providing critical insight into the concrete’s workability, stability, and resistance to segregation.

The V Funnel test is essential when designing SCC mixes that must flow through heavily reinforced or congested formwork. By recording the time taken for concrete to completely discharge from the funnel, the apparatus allows engineers and technicians to quickly judge whether a mix is too stiff, too viscous, or optimally balanced.

Manufactured with a durable, corrosion-resistant metal body and a precise quick-release gate mechanism, AZA1111 ensures smooth, repeatable testing. Its rigid structure and stable stand make it suitable for both laboratory and site-based quality control environments.

The equipment is designed in compliance with EN 12350-9 and EFNARC guidelines, ensuring globally accepted and repeatable test results
