CAPPING SET (HORIZONTAL) AZA1163
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).
CAPPING SET (VERTICAL) AZA1164
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).
CHASE AIR INDICATOR AZA1105
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.

It is especially suitable for Self-Compacting Concrete (SCC), precast concrete, and high-consistency mixes where the traditional slump test is not effective.
This test set works by allowing a freshly mixed concrete sample to spread under controlled, repeated vertical jolts of a mechanically calibrated table. The final spread diameter of the concrete is measured to assess its flowability and uniformity.
Built with a rigid, precisely machined table surface, the AZA1110 ensures repeatable and reliable results. Its heavy-duty construction allows long-term use in demanding laboratory environments while remaining easy to clean, store, and maintain.
The apparatus complies with major international standards including IS 1199, ASTM C1437, and BS EN 12350-5, making it suitable for both domestic and international testing requirements.
The word concrete comes from the Latin word “concretus” that means compact or condensed; in fact it is well known that since the second century the Romans mixed quicklime with pozzolan to enhance its hydraulic properties and then mixed it with aggregates in order to obtain a robust stone-like material for the construction of roads and structures. Since then the quality and the production technology of concrete strongly evolved hence considerable care supported by knowledge is required to produce quality concrete. Accurate Business, since several years manufacturer leader of testing equipment, proposes a complete range of testing equipment to satisfy practically all the EN and other National Standards.
