V FUNNEL AZA1111

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.

AZA1109 J-Ring – Narrow Gap is a precision testing apparatus designed to evaluate the passing ability of Self-Compacting Concrete (SCC) under highly restrictive conditions. This device simulates densely congested reinforcement zones by creating artificial obstructions that the fresh SCC must flow through without blocking or segregating. It is an essential tool for determining whether SCC mixes are suitable for heavily reinforced structural elements such as beams, columns, and shear walls.

The narrow gap design offers a more stringent test compared to standard J-Rings, allowing engineers and quality control professionals to accurately observe flow diameter, T50 flow time, and blocking behavior. When used in combination with a standard slump flow cone, AZA1109 provides reliable, repeatable results that help optimize mix designs and ensure consistent on-site performance.

Manufactured from durable, corrosion-resistant steel, the AZA1109 is built for repeated use in laboratory and field testing environments. The apparatus is fully compliant with ASTM C1621 and EFNARC guidelines, ensuring internationally accepted testing procedures.

The AZA1106 Kelley Ball Penetration Apparatus is a precise and durable instrument used to determine the workability of fresh concrete through direct steel ball penetration. Considered an effective alternative to the slump test, it provides a quantitative, repeatable, and non-disruptive measurement of concrete consistency, making it ideal for both laboratory and field applications. Engineered with robust materials and compliant with ASTM C360, this apparatus ensures consistent performance, long service life, and ease of use in demanding construction and testing environments.
