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

CONCRETE FLOW TABLE TEST SET AZA1110
AZA1110 Concrete Flow Table Test Set is a precision-engineered laboratory apparatus designed to determine the workability, consistency, and flow characteristics of fresh concrete. 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.
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.
