The RapidAir is an image analysis system for automatic and quick determination of the air void structure parameters in hardened concrete based on the ASTM C457 or EN 480-11 standard methods.

Applications:

  • Determine the total air content, spacing factor, and specific surface in hardened concrete.
  • Effectively and rapidly study and quantify the air void system: volume, spacing, and size distribution of the air bubbles.

Description:

A concrete sample cut, grinded, polished, and tinted in the laboratory is mounted on a moving X-Y-Z stage positioned below a video camera. The RapidAir control unit automatically moves the stage, and the software determines the portion of the total traverse length that passes through the white air voids. The measurement is done within 12 min for linear traverse analysis and within 30 min for modified point count.
After the scan is completed, the air-void parameters are calculated as per ASTM C457 or EN 480-11. In addition, graphical presentation of the air-void distribution and the raw data are available.

Applications:

  • Determine the total air content, spacing factor, and specific surface in hardened concrete.
  • Effectively and rapidly study and quantify the air void system: volume, spacing, and size distribution of the air bubbles.

Specifications:

  • X,Y,Z-stage with electronic stepper motor for accurate X-Y displacement, 230/120 VAC, equipped with emergency switch
  • LED ring lightening system
  • Color digital camera, 2 mm resolution
  • Microscope objective for op to 100x magnification
  • Windows based software with user friendly interface
  • Self-calibration with a reference sample
  • Exporting of data to MS Excel
  • Print out reports for ASTM C 457 and EN 480-11.
