DENSITY OF FRESH AND HARDENED CONCRETE AZA1132
The Azalab Density Apparatus AZA1132 is a precision-engineered system designed to measure the density of both fresh (plastic) and hardened (cured) concrete. Conforming to IS 1199 and ASTM C642, it is essential for material testing laboratories, construction quality assurance teams, and field technicians who require accurate and consistent density evaluations.
Density is a key parameter that influences concrete strength, durability, compaction quality, and structural performance. The AZA1132 enables reliable assessment at every stage of the concrete lifecycle—ensuring mix design accuracy, detecting voids, and verifying on-site production consistency.

Description
Technical Overview
Fresh Concrete Density
Using a calibrated density container:
-
Fill, rod, or vibrate the container to eliminate air voids
-
Record weight
-
Compute density using weight ÷ volume
This process verifies mix uniformity, yield, and air content control.
Hardened Concrete Density
Using water displacement (Archimedes’ method):
-
Weigh specimen in air
-
Weigh specimen in water using suspension frame
-
Volume and density are computed from the difference
This identifies internal deficiencies such as voids, honeycombing, or poor compaction.

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.
