The Azalab Horizontal Capping Set is a precision-engineered apparatus designed for preparing 150 mm concrete cube specimens for compressive strength testing. By ensuring flat, smooth, and perfectly parallel end surfaces, the system enables highly accurate and repeatable test results in compliance with ASTM C617 and IS 516 requirements.

Enhanced Ergonomics & Operational Control

This horizontal version is particularly suited for busy laboratories that prioritize operator comfort, safe handling of molten capping compounds, and efficient sample processing. With the cube placed on its side, technicians gain better access to the exposed surface, simplifying the controlled pouring of sulfur or gypsum-based capping materials. The horizontal layout also minimizes spill risks and enhances workflow during continuous testing operations.

Robust Construction & Precision Alignment

Manufactured from powder-coated heavy-duty steel, the frame is designed for long-term laboratory use. The precision-machined steel base ensures proper seating and alignment of the cube, eliminating tilt or misalignment that could compromise test accuracy. The single-slot holder keeps the specimen firmly in place during the capping process.Once the first face is capped and cured, the cube is rotated to prepare the opposite surface. After both ends are perfectly level and parallel, the specimen is ready for compressive strength testing in a Universal Testing Machine (UTM).

The AZA-LAB Vertical Capping Set is a precision tool designed to prepare 150 mm concrete cube specimens with smooth, level, and parallel end surfaces prior to compressive strength testing. By holding the specimen upright and ensuring perfect alignment, this apparatus enables consistent and accurate results in accordance with ASTM C617 and IS 516.

Purpose & Function

During compressive strength testing, concrete cubes must have properly prepared surfaces to guarantee uniform load transfer between the testing platens. Any irregularity can cause stress concentrations or premature failure. The Vertical Capping Set provides a stable, guided fixture that maintains the cube in a perfect vertical orientation while capping compound is applied to each end.

Once sulfur or gypsum-based capping material is poured and allowed to harden, the ends become flat, parallel, and ready for precise compression testing in a Universal Testing Machine (UTM).

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.
