For Accurate Air Content Measurement in Fresh Concrete
The AZA1145 B-Type Air Entrainment Meter is a durable, lab-grade instrument designed to determine the percentage of entrained air in freshly mixed concrete using the pressure method. Air entrainment is a critical parameter for ensuring workability, longevity, and freeze-thaw resistance of concrete—especially for structures exposed to harsh environmental conditions.
Applications
Widely used across the concrete testing sector, the AZA1145 is ideal for:
- Civil construction quality-control laboratories
- Cement and concrete R&D departments
- Ready-mix concrete testing facilities
- Engineering colleges and training institutes
- Material testing and QA/QC divisions
Why Air Entrainment Testing Is Important
Entrained air improves:
- Workability of fresh concrete
- Durability in freeze–thaw conditions
- Resistance to scaling, cracking, and surface deterioration
Accurate measurement ensures compliance with mix design specifications, verifies performance of air-entraining agents, and supports high-quality concrete production.
With AZA1145, labs can confidently:
- Confirm mix design compliance
- Validate field concrete quality
- Optimize concrete mixes for extreme environments

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.

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.
