RapidAir 457

Model:RapidAir

Use:Automatic test of air void distribution in hardened concrete in less than 10 minutes in your laboratory

Standard:

The RapidAir 457 equipment provides an automatic system for analyzing the air content in hardened concrete. The analysis time with the RapidAir 457 system is less than 10 minutes, which should be compared to the 4-6 hours normally required for manual analysis with conventional types of equipment.

The system can replace the manual test performed as described in the ASTM designation C457/C457M-16 procedure A, B and C “Standard Test Method for Microscopical Determination of Parameters of the Air-Void System in Hardened Concrete” or the test performed according to EN 480-11 “Determination of air void characteristics in hardened concrete”. All methods include specifications for grinding, and polishing a plane section of concrete, and for measuring the air void distribution with the use of a microscope according to the linear traverse method and modified point count.

Advantages

·         Increased productivity

·         Operator independent

·         Excellent repeatability

·         Excellent reproducibility

·         Good accuracy

Hardware and Software

The RapidAir 457 test equipment consists of an automatic analysis system comprising a computerized control unit (PC) with a flat panel monitor, a digital camera, a microscope objective mounted on a moving stage, and a user friendly analysis software operating in a MS-Windows environment. The RapidAir 457 system has a resolution better than 2 microns, a magnification of about 100x, and is delivered pre-configured, aligned, tested, and ready for Plug-and-play use. The interface is user friendly allowing the daily operations to be handled in an easy and logical fashion that minimizes the risk of analysis or reporting errors.
