Ultrasonic Concrete Tester AZA 1151-B
The Ultrasonic Concrete Tester (UCT – Model 1151 B) from AZA Lab is a fully portable, non-destructive testing instrument for assessing the strength and quality of concrete, either in-situ or precast. Designed with field conditions in mind, it combines simplicity, accuracy, and unmatched stability, making it ideal for construction sites, laboratories, and quality control applications.
The instrument generates low-frequency pulses and measures the time of flight through concrete. This time measurement is then used to calculate ultrasonic pulse velocity, which is directly related to the mechanical strength of concrete.

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.
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.
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.
L SHAPE BOX APPARATUS AZA1112
AZA1112 L Shape Box Apparatus is a precision testing device designed to evaluate the passing ability and flow performance of Self-Compacting Concrete (SCC) in congested reinforcement conditions. This apparatus simulates real-world scenarios such as densely reinforced beams, columns, tunnels, and bridge segments, where concrete must flow freely without segregation or blockage.
The distinctive L-shaped design creates a controlled flow path where freshly mixed SCC moves from a vertical chamber into a horizontal channel containing reinforcement bars. By measuring the concrete heights at both ends (H1 and H2), the H2/H1 ratio is calculated, providing a direct, quantitative assessment of the concrete’s ability to pass through obstructions.
Manufactured from durable, corrosion-resistant steel, AZA1112 is built for long-term laboratory and site use. It conforms to EN 12350-10 and EFNARC guidelines, ensuring global acceptance of test results.
SLUMP CONE, PLASTIC AZA1103
AZA1103 Slump Cone (Plastic) is a durable and lightweight testing tool designed for accurate measurement of concrete workability and consistency. It is widely used in construction sites, civil engineering laboratories, and quality control departments for fast and reliable slump testing of fresh concrete mixes.
Unlike traditional metal cones, this model is manufactured from high-quality rigid plastic, making it corrosion-resistant, dent-proof, and highly suitable for repeated field and laboratory use. Its lightweight construction makes it easy to transport and ideal for site engineers and mobile testing teams.
The apparatus is manufactured to standard dimensions and fully complies with IS 1199 and ASTM C143, ensuring accurate and repeatable test results. The smooth internal surface minimizes friction, allowing easy release of concrete and improving measurement accuracy.
This slump cone helps engineers quickly determine if a concrete mix has the correct consistency for placement, compaction, and finishing. It is especially useful for quality checks before concrete pouring to avoid honeycombing, segregation, or improper flow.
AZA1103 is reusable, easy to clean, and requires minimal maintenance, making it a long-lasting and cost-effective solution for routine concrete testing.
