Corrosion of concrete steel reinforcement is the primary factor influencing the durability of concrete. According to statistics, the durability damage of concrete caused by corrosion of reinforcing steel accounts for more than 40% of all damage, and chloride ion erosion is the main cause of steel corrosion. The DTL Concrete Chloride Ion Flux Tester is used to measure concrete penetration resistance (compactness), an important index for durability of concrete. The test index is the 6-hour electric flux value (coulomb) of the concrete test piece, which is fast. Evaluate the ability of concrete to resist the penetration of chloride ions.

Chloride ion is an important factor in inducing corrosion of steel bars. In order to avoid premature corrosion of steel bars, the control of chloride ion content in concrete raw materials is quite strict. China's relevant regulations clearly require that when concrete is used to mix concrete raw materials such as sand, aggregates, cement, admixtures, and mixing water, it is necessary to carry out the test of chloride ion content to fundamentally avoid the introduction of excess chloride ions into the concrete. The test of chloride ion content in structural concrete plays an important role in the evaluation of structural safety, and at the same time provides a reference value for the reconstruction and repair of old structures.
