Explanation:
Durability is one of the most important properties of concrete as well as strength. It depends on the type of building and environmental conditions. Especially in road construction, high resistance to freeze-thaw cycles is of great importance and is therefore one of the most important criteria in testing. The CDF / CIF test ensures that the freeze-thaw test is performed in accordance with the CDF recommendations of Rimem. The advantage of this test method is that the results given are very good reproducibility. With this test procedure, the amount of wear of a surface is measured by a series of freeze-thaw cycles. Thus, the test samples are placed in a sodium chloride solution to take effect on its surface. The result gives an estimate for resistance to the freeze-dissolution cycle for the concrete being tested.
