PERMEABILITY APPARTUS (THREE CELL MODEL) AZA1143

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.

AZA1108 ISAT Apparatus is a precision-engineered testing instrument designed to measure the Initial Surface Absorption of hardened concrete. This test is essential for evaluating the durability of concrete by determining how quickly water penetrates the surface under controlled conditions. The apparatus is widely used in civil engineering laboratories and quality control departments to assess permeability and long-term performance of concrete structures exposed to moisture.

Built with a high-accuracy capillary tube system, the AZA1108 maintains a constant water head over a defined test area and records the volume of water absorbed over specific time intervals — typically at 10, 30, and 60 minutes. The readings obtained help engineers understand the surface porosity of concrete, which is a critical indicator of resistance against weathering, chloride ingress, corrosion of reinforcement, and environmental deterioration.

Designed in compliance with BS 1881-208, this apparatus ensures reliable, repeatable, and standard-compliant results. Its sturdy, rust-proof construction and easy-to-use configuration make it ideal for both routine testing and advanced durability studies in construction material laboratories.

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 Azalab Mould Verification Toolset is a precision-engineered quality control kit designed for verifying the dimensional accuracy and geometric tolerances of concrete casting moulds and test specimens. It is an essential instrument set for laboratories conducting routine QC, R&D, and compliance testing in accordance with IS, ASTM, EN, and BS standards. This complete toolset ensures that cube moulds, beam moulds, and cylindrical moulds meet the required tolerances for flatness, perpendicularity, straightness, and dimensional conformity—parameters that directly impact test reliability and reproducibility. Key Capabilities The AZA1121 verification kit allows accurate measurement of:

• Flatness of mould and specimen surfaces
• Straightness along mould edges and specimen sides
• Perpendicularity of internal walls and corners
• Dimensional accuracy (L × W × H, and diameter for cylinders)
• Go/No-Go tolerance checks for standardized cube mould sizes
• Surface deviation & gap measurement using feeler gauges

Each instrument is manufactured using precision-ground stainless steel or hardened, anodized aluminum, ensuring long-term stability and high measurement accuracy.
