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

INITIAL SURFACE ABSORPTION TEST (ISAT) APPARATUS AZA1108
AZA1108 ISAT Apparatus is a precision-engineered testing instrument designed to measure the Initial Surface Absorption of hardened concrete. This test is essential for evaluating the durability of concrete by determining how quickly water penetrates the surface under controlled conditions. The apparatus is widely used in civil engineering laboratories and quality control departments to assess permeability and long-term performance of concrete structures exposed to moisture.
Built with a high-accuracy capillary tube system, the AZA1108 maintains a constant water head over a defined test area and records the volume of water absorbed over specific time intervals — typically at 10, 30, and 60 minutes. The readings obtained help engineers understand the surface porosity of concrete, which is a critical indicator of resistance against weathering, chloride ingress, corrosion of reinforcement, and environmental deterioration.
Designed in compliance with BS 1881-208, this apparatus ensures reliable, repeatable, and standard-compliant results. Its sturdy, rust-proof construction and easy-to-use configuration make it ideal for both routine testing and advanced durability studies in construction material laboratories.
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.
