Analyzing the air void content and distribution in hardened concrete is a key component when evaluating the susceptibility of concrete during freezing and thawing cycles.
The HS-745T Air Voids Analysis System is used to facilitate the counting of microscopic air void content, frequency, spacing factor and paste-air ratio in concrete.
- Complies with ASTM C457 specifcations and MTO LS-431
- Procedure A, The Linear Traverse Method
- Procedure B, The Modifed Point-Count Method
The HS-745T Air Voids Analysis System includes:
Shown with optional PC, video camera and viewing software.
- High quality Nikon trinocular microscope with the option to add a video camera and viewing software to be used with a PC
- Nikon fiber optic illuminator produces 150 watts of high-intensity cold light illumination
- Lamp life of over 1,000 hours
- Proprietary design of the manual stage links both the X and Y axes in a single piece of metal for excellent rigidity and superior accuracy
- Patented steel friction drive ensures smooth, backlash-free operation
- 5 position counter assists in keeping count of parameters being analyzed
ASTM C457 describes sample preparation equipment for grinding and polishing a plane section of concrete prior to measuring the air void distribution with the use of a microscope. Hoskin Scientific can provide you with a complete turn key system which include all necessary items to perform the air-void determination of concrete. Please contact us for full details.
