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.
