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
