Concrete & Cement Testing Equipment - Rapid Freeze-Thaw Test Chambers – ASTM C666 Concrete Durability Testing
Rapid Freeze-Thaw Test Chambers – ASTM C666 Concrete Durability Testing
ToronRFTC-Series Rapid Freeze-Thaw Test Chambers are advanced and fully automated systems designed for accurate concrete freeze-thaw testing, in accordance with ASTM C666 – Standard Test Method for Resistance of Concrete to Rapid Freezing and Thawing.
These chambers are essential for evaluating the freeze-thaw resistance and long-term durability of concrete, especially in cold climate applications where cyclic freezing and thawing can severely affect performance.
Available in three configurations, these concrete test machines provide scalable solutions for quality control labs, construction material testing centers, and academic research facilities.
Precise, Repeatable Freeze-Thaw Testing
The ToronRFTC Rapid Freeze-Thaw Test Chamber uses programmable temperature control to simulate repeated freezing and thawing cycles — a crucial test for evaluating the durability of concrete under thermal stress. The system maintains tight temperature uniformity and accurate cycle timing to ensure consistent, repeatable results every time.
