COMPACTION FACTOR APPARATUS AZA1107
Precision Workability Tester for Low-Slump Concrete
The AZA1107 Compaction Factor Apparatus from Azalab is engineered for accurate assessment of the workability of very dry or low-slump concrete mixes, where conventional slump testing is ineffective. Conforming to IS 1199 and BS 1881 Part 103, it is an essential instrument for concrete laboratories, research institutions, precast units, and field quality control.
Designed with rugged construction and a standardized double-hopper mechanism, the apparatus provides a quantitative compaction factor by comparing partially compacted and fully compacted concrete weights—ensuring high reliability and repeatability.
Key Features
- Precision measurement of compaction factor for dry and stiff concrete
- Double-hopper system with smooth trap release
- Conforms to IS 1199 and BS 1881 standards
- Suitable for precast plants, RMC units, and civil engineering labs
- Rugged, powder-coated mild-steel construction
- Cylindrical container included for final measurement
Portable and easy to assemble at field locations
Description
How the Test Works
The apparatus consists of two conical hoppers positioned above a cylindrical receiving container.
- Fill the top hopper with fresh concrete and strike off.
- Release the trap door to allow concrete to fall into the lower hopper.
- Immediately open the second trap to discharge concrete into the cylindrical container.
- Weigh the concrete (Partially Compacted Weight).
- Refill and compact the cylinder in layers to obtain the Fully Compacted Weight.
Compaction Factor = Partially Compacted Weight / Fully Compacted Weight
Typical values range from 0.70 to 0.95, depending on mix stiffness.
Applications
- Dry or low-slump concrete mixes
- Precast concrete blocks, pipes, sleepers
- Road construction mixes
- Research laboratories and QC departments
- Comparative workability studies

J-RING, NARROW GAP AZA1109
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.
K-SLUMP TESTER AZA1104
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
