Freeze-Thaw Concrete Testing
Freeze Thaw Cabinet, Elite Series
Used to measure the resistance of concrete to deterioration caused by repeated cycles of freezing and thawing.
Resonance Test Gauge
The Resonance Test Gauge is used for Flexural and torsional resonance testing of concrete, rock, asphalt and masonry.
E-Meter for Flexural Resonance of Concrete
Determine flexural resonance of concrete under accelerated freezing and thawing cycles
Super Air Meter
The Super Air Meter measures both air void spacing and air volume of plastic (fresh) concrete
CAPE TANK System for Super Air Meter
The CAPE Tank Accessory simplifies pressurization of the H-2784 Super Air Meter during testing
Key features of the Freeze-Thaw include:
- Fully automatic operation frees operator to perform other lab duties.
- Allows users to establish field control using correlations between concrete strength and durability
- Permits the evaluation of variables in concrete properties and conditioning.
- Useful in the evaluation of the durability of aggregates, as well as the properties of admixtures.
The Sonometer determines changes in resonant frequency of concrete specimens subjected to alternate cycles of freezing and thawing with the Humboldt freeze-thaw cabinet. This apparatus closely follows design parameters set up over 40 years ago by the Portland Cement Association research laboratories. The original PCA design has been modified by changing to solid state circuitry and addition of a built-in cathode ray oscilloscope. No other resonant frequency system includes an oscilloscope despite being strongly recommended in ASTM C215 paragraph 4.2. Other systems offer an oscilloscope connection. The oscilloscope confirms that peak reading on meter is actual resonance and not a harmonic.
