SAND ABSORPTION CONE AND TAMPER AZA1131

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.

AZA1104 K-Slump Tester is a fast, reliable, and non-destructive testing device designed to measure the workability and consistency of fresh concrete directly at construction sites or in laboratory environments. It provides instant slump approximation without the need for traditional slump cones, base plates, or tamping rods, making it an essential tool for modern concrete quality control.

This handheld instrument is widely used by civil engineers, site technicians, and quality inspectors who require quick, repeatable, and real-time results during concrete batching, transportation, and placement. Its simple design eliminates complicated setup, reducing testing time and operator fatigue.

Manufactured from high-grade stainless steel, the probe is corrosion-resistant and suitable for harsh site conditions. The etched scale markings provide direct readings in millimeters or inches, allowing accurate penetration depth measurement without additional instruments.

Unlike traditional slump testing methods, the AZA1104 enables non-destructive testing, meaning the concrete surface remains intact and usable after testing. This feature is especially useful when multiple checks are needed during large pours or continuous batching operation

The Azalab AZA1128 Polyurethane Beam Mould Series is engineered for casting concrete beam specimens used in flexural strength tests. Built from high-impact, shock-absorbing polyurethane, these moulds deliver exceptional durability, dimensional accuracy, and ease of handling. Their lightweight yet robust design makes them suitable for both laboratory and field applications.

Polyurethane offers superior resilience compared to traditional metal or rigid plastic alternatives, enabling these moulds to withstand vibration, repeated use, and environmental exposure. The smooth internal finish ensures clean, damage-free demoulding, while the mould structure maintains consistency across multiple cycles.

Each AZA1128 mould complies with IS 516, ASTM C78, and BS 1881, ensuring reliable and standardized test preparation.

The AZA1120 Precision Steel Straight Edge is a laboratory-grade tool engineered for leveling, scraping, and finishing concrete and soil specimens during testing procedures. Used extensively in concrete cube/cylinder preparation, slump cone tests, and air meter testing, this straight edge ensures flat, uniform specimen surfaces essential for accurate and repeatable results.

Manufactured from high-grade hardened steel, the AZA1120 offers superior rigidity, dimensional stability, and long-term durability. The flat, 1-inch wide, 12-inch long bar profile allows smooth handling and effortless removal of excess material from molds. A corrosion-resistant polished or matte finish further enhances longevity and reliability in both lab and field conditions.
