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.

• The AZA1143 Permeability Apparatus is a laboratory-grade soil testing system designed to determine the coefficient of permeability of various soil types with high accuracy. Built for geotechnical engineers, soil laboratories, academic institutions, and construction quality control centers, this three-cell unit supports simultaneous testing of three samples, significantly improving efficiency and comparative analysis.Engineered for both constant head (coarse soils) and falling head (fine soils) test methods, the AZA1143 ensures reliable results aligned with IS 2720 (Part 17). Its corrosion-resistant construction and precision acrylic permeability cells deliver stable performance, visual clarity, and long-term durability.

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 AZA1167 Poker Vibrator with Vibrating Table is a dual-function concrete compaction system designed for laboratory applications where high precision, uniformity, and compliance with testing standards are essential. This integrated setup combines internal (needle) vibration with surface/table vibration, enabling superior compaction for concrete cubes, cylinders, beams, and specialty moulds.

Concrete compaction is a critical step in laboratory sample preparation. Improperly compacted concrete contains air voids that significantly reduce compressive strength and compromise test reliability. The AZA1167 system resolves these challenges by offering both internal and external vibration methods in a single platform, streamlining workflows and producing consistent, repeatable results.

The Poker Vibrator uses a high-frequency needle (25 mm) to penetrate fresh concrete and eliminate trapped air. Meanwhile, the Vibrating Table provides uniform surface vibrations ideal for cube moulds, cylinder moulds, and specimens that require gentle but effective compaction. Both units can be operated independently or simultaneously, depending on the testing requirement.

Built with a sturdy powder-coated steel frame, rubber-mounted vibration isolation, and corrosion-resistant components, the AZA1167 is engineered for long-term durability in high-throughput concrete laboratories. It conforms to ASTM C31/C31M and IS 1199 standards for concrete sampling and compaction, ensuring suitability for accredited testing facilities.

Advanced Six-Cell System for Concrete Durability Evaluation
ASTM C1202 Compliant – Rapid Chloride Ion Penetration Testing

The AZA1144 Rapid Chloride Permeability Tester is a high-precision durability assessment system engineered to measure the resistance of concrete to chloride ion penetration. Chloride permeability is a critical parameter in determining long-term durability, especially for structures exposed to marine environments, saltwater spray, de-icing salts, and chemical-rich industrial zones.

Designed for research laboratories, material testing centers, infrastructure quality control units, and academic institutions, the AZA1144 enables users to perform Rapid Chloride Permeability Tests (RCPT) strictly in accordance with ASTM C1202. This rapid method provides concrete permeability results within six hours, significantly reducing the time required compared to traditional testing methods.
