CRACK WIDTH RULER AZA1147

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.

AZA1112 L Shape Box Apparatus is a precision testing device designed to evaluate the passing ability and flow performance of Self-Compacting Concrete (SCC) in congested reinforcement conditions. This apparatus simulates real-world scenarios such as densely reinforced beams, columns, tunnels, and bridge segments, where concrete must flow freely without segregation or blockage.

The distinctive L-shaped design creates a controlled flow path where freshly mixed SCC moves from a vertical chamber into a horizontal channel containing reinforcement bars. By measuring the concrete heights at both ends (H1 and H2), the H2/H1 ratio is calculated, providing a direct, quantitative assessment of the concrete’s ability to pass through obstructions.

Manufactured from durable, corrosion-resistant steel, AZA1112 is built for long-term laboratory and site use. It conforms to EN 12350-10 and EFNARC guidelines, ensuring global acceptance of test results.

The AZA1117 Laboratory Pan Mixer (40 Litres) is engineered for precise, consistent, and repeatable mixing of concrete, mortar, and cement paste in controlled laboratory environments. Designed for durability and high-performance blending, this mixer supports material testing, R&D applications, and academic laboratory work where uniformity and accuracy are essential. Built with a heavy-duty steel pan, gear-driven mixing mechanism, and adjustable blades, the AZA1117 ensures superior mix homogeneity even with coarse aggregates up to 20 mm. Its robust 2 HP motor and 3-phase drive deliver uninterrupted power for demanding laboratory workloads.

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.
