Material Testing Equipment

AZA1105 Chase Air Indicator is a compact, lightweight, and highly practical field instrument designed to measure the air content in freshly mixed concrete. It is widely used in construction sites where rapid quality decisions are required and laboratory testing equipment is not readily available.

This device serves as a reliable field alternative to standard air content methods such as ASTM C231 (Pressure Method) and ASTM C173 (Volumetric Method). While it is not intended to replace laboratory-grade instruments, it provides fast, useful guidance that helps engineers and site supervisors maintain proper concrete mix quality.

Air entrainment plays a critical role in concrete durability, especially in regions exposed to freeze–thaw cycles, and contributes significantly to workability and pumpability of concrete. AZA1105 helps ensure that air content remains within the recommended range (typically 4%–7%), reducing the risk of weak or brittle concrete.

The working principle is based on fluid displacement and vacuum pressure balance. A representative mortar sample is collected and placed inside the testing chamber, where a controlled vacuum is applied. The internal pressure difference is translated directly to a calibrated dial gauge showing the approximate air content percentage.

With no electrical components, moving mechanical assemblies, or complex maintenance requirements, the AZA1105 is extremely reliable and built for tough field conditions. Its rugged body and easy-to-read dial make it suitable for continuous daily use in real-world jobsite environments.

The AZA1141 Integrated Concrete Strength Testing System is a multifunctional, heavy-duty testing solution combining compression testing, flexural testing, and splitting tensile testing in a single, robust machine. Engineered for high accuracy, reliability, and compliance with global standards, it is ideal for laboratories, research facilities, QC departments, and construction material testing centers requiring a complete mechanical testing suite within one compact frame.

This advanced system is designed to evaluate:
• Compressive strength of concrete cubes and cylinders (ASTM C39)
• Flexural strength of concrete beams (ASTM C78)
• Indirect tensile strength using the splitting tensile test (ASTM C496)

A unified hydraulic or servo-controlled loading frame ensures precise, stable load application across all test modes. Interchangeable jigs, platens, and beam fixtures enable rapid switching between test types, significantly improving laboratory productivity. Each frame is constructed using high-strength, corrosion-resistant steel with precision machining to maintain alignment and load accuracy even under extreme capacities (1000–3000 kN).

Advanced variants include digital control consoles with PC connectivity, real-time graphing, and automated data acquisition, while manual models cater to field or budget-oriented labs.

The AZA1133 Compression Testing Machine is a robust, hand-operated channel-frame system engineered to deliver accurate and repeatable compressive strength measurements for concrete cubes, cylinders, bricks, blocks, and similar construction materials. Designed with a heavy-duty C-channel welded frame, this unit ensures outstanding rigidity, minimal deflection, and long service life, making it ideal for quality control labs, construction sites, research institutions, and material testing facilities. The machine conforms to IS 516 and BS 1881 requirements for compression testing and maintains precise alignment through a self-adjusting spherical seat on the upper platen. Manual load application is facilitated through a central hydraulic jack and precision lead screw assembly. All platens are hardened, machined, and mirror-polished, providing uniform load transfer and repeatable results.
