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.

The AZA1123 Cylindrical Mould is a precision-engineered, heavy-duty mould designed for casting standardized cylindrical concrete specimens used for compressive strength, split tensile strength, and durability testing. It is an essential tool for construction material testing labs, civil engineering institutions, and quality control facilities that routinely evaluate concrete performance. Built for repeatable use and dimensional stability, the AZA1123 ensures uniform specimen geometry in accordance with IS, ASTM, and ACI guidelines, making it a dependable choice for compliance testing and research applications.

Purpose & Function

The cylindrical mould is used to prepare concrete specimens of standard dimensions, typically:

• 150 mm diameter × 300 mm height
• 100 mm diameter × 200 mm height

These specimens are used to perform:

• Compressive strength tests
• Split tensile strength tests
• Elastic modulus evaluations
• Durability and material behavior studies

Accurate geometry ensures that the applied load is uniformly transferred, resulting in consistent and valid test outcomes.

The AZA1116 Motorised Laboratory Concrete Mixer is a high-performance mixing solution engineered to deliver consistent, repeatable, and uniform concrete batches for laboratory applications. Built to meet the needs of material testing facilities, civil engineering departments, R&D centers, and government labs, this mixer ensures reliable preparation of concrete for compressive strength tests, workability assessments, and research studies. Designed with a durable rotating drum, heavy-duty mixing blades, and a robust motor, the AZA1116 provides exceptional blending efficiency while maintaining operational safety and user convenience.

AZA1103 Slump Cone (Plastic) is a durable and lightweight testing tool designed for accurate measurement of concrete workability and consistency. It is widely used in construction sites, civil engineering laboratories, and quality control departments for fast and reliable slump testing of fresh concrete mixes.

Unlike traditional metal cones, this model is manufactured from high-quality rigid plastic, making it corrosion-resistant, dent-proof, and highly suitable for repeated field and laboratory use. Its lightweight construction makes it easy to transport and ideal for site engineers and mobile testing teams.

The apparatus is manufactured to standard dimensions and fully complies with IS 1199 and ASTM C143, ensuring accurate and repeatable test results. The smooth internal surface minimizes friction, allowing easy release of concrete and improving measurement accuracy.

This slump cone helps engineers quickly determine if a concrete mix has the correct consistency for placement, compaction, and finishing. It is especially useful for quality checks before concrete pouring to avoid honeycombing, segregation, or improper flow.

AZA1103 is reusable, easy to clean, and requires minimal maintenance, making it a long-lasting and cost-effective solution for routine concrete testing.
