TDR-Ⅲ concrete rapid freeze-thaw test chamber

Product Overview

The Concrete Rapid Freeze-Thaw Test Chamber is particularly suitable for cement concrete tests with high requirements for frost resistance, and for measuring the ability of cement concrete to resist repeated effects of water and negative temperature. It is suitable for cement concrete frost resistance tests with dynamic elastic modulus, mass loss rate and relative durability index as evaluation indicators. The instrument can meet the test requirements of the "Highway Engineering Cement Concrete Test Procedure" (JTGE30-2005), concrete frost resistance test (fast freezing method) (T0565-2005), and international GBJ82-85.
