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.

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.


Construction & Components

  • Calibrated Density Container (1L or 3L) – steel or plastic variants

  • Weighing Scale (digital/manual)

  • Suspension Frame for immersion tests

  • Water Tank/Bucket

  • All parts corrosion-resistant and lab/field durable
