CONCRETE CURING RACKS AZA1157

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 AZA1118 Labomix Concrete Pan Mixer is designed for demanding, high-volume mixing operations in construction laboratories, R&D facilities, and material testing centers. Built for durability and precision, it delivers consistent blends of concrete, mortar, grout, and aggregate mixes while supporting rigorous IS/ASTM test procedures.

Engineered with a high-efficiency gear-driven transmission, it provides stable torque, low maintenance requirements, and excellent mixing uniformity. The unit is available in multiple capacities from 90 litres to 300 litres, enabling users to select suitable volume for their operational needs.

The mixer features exchangeable mixing shovels, a safe-locking automatic discharge system, and large mobility wheels that allow a single operator to handle batching, mixing, and discharging efficiently.

The AZA1126 Plastic Cube Mould is a precision-engineered solution designed for casting 150 mm × 150 mm × 150 mm concrete cubes used in compressive strength testing. Manufactured from high-impact, corrosion-resistant plastic, this mould offers an excellent balance of durability, ease of use, and portability—making it ideal for laboratories, construction sites, and training institutes. Its modular construction, consisting of detachable side walls and a sturdy base, allows for fast assembly and easy demoulding. The smooth internal surface ensures the concrete cube is removed cleanly without surface defects, supporting consistent, repeatable test results. Unlike metal moulds, the AZA1126 is lightweight, rust-free, and requires minimal maintenance, even in humid or coastal environments. The mould complies with IS 10086 and BS 1881-108, ensuring suitability for standardized concrete compressive strength testing procedures.

The AZA1120 Precision Steel Straight Edge is a laboratory-grade tool engineered for leveling, scraping, and finishing concrete and soil specimens during testing procedures. Used extensively in concrete cube/cylinder preparation, slump cone tests, and air meter testing, this straight edge ensures flat, uniform specimen surfaces essential for accurate and repeatable results.

Manufactured from high-grade hardened steel, the AZA1120 offers superior rigidity, dimensional stability, and long-term durability. The flat, 1-inch wide, 12-inch long bar profile allows smooth handling and effortless removal of excess material from molds. A corrosion-resistant polished or matte finish further enhances longevity and reliability in both lab and field conditions.
