Air Content Meters for Fresh Concrete
Air content meters for fresh concrete are used in quality control of concrete mixes, particularly with respect to workability, durability and structural resistance. A properly adjusted and calibrated instrument is essential for reliable determination of the air volume in concrete according to the requirements of technical standards.
Metrological activities for air content meters
- Calibration of air content meters for fresh concrete according to STN EN 12350-7.
- Functional check and assessment of technical condition; if required, cleaning of the vessel (price according to the current price list).
- Determination of the volume of the test vessel for fresh concrete density tests by the gravimetric method, up to 10 dm³.
- Calibration of the air-co
