C189 Concrete workability meter

( Concrete )

  • NF P18-452

The concrete workability meter (also known as plastometer) is designed to test concrete for dynamic workability.
It is suitable for field and laboratory tests to check:

  • concrete mix for consistency, expecially water content
  • optimum proportioning of concrete constituents (sand, gravel, water, cement)
  • possible improvment when admixing a plastifier
  • comparing two concrete types

The unit consists of a prismatic receiver divided into two unequal volumes by a removable partition, and an electric vibrator.
The fresh concrete is poured into the large volume space, the separating partition is removed, and the vibrator starts automatically.
The test consists in measuring the time required for the concrete to reach an uniform distribution in the receivers.

Power supply: 230V 1ph 50Hz 300W
Dimensions: 820x420x410 mm
Weight: 80 kg approx.
