Assess concrete durability and protect reinforcement using ASTM C1202 testing to control chloride ion penetration and extend structural life.
Reinforced concrete structures are highly sensitive to corrosion, especially in aggressive environments where chloride ions are present, such as coastal areas or regions exposed to de-icing salts. Chloride penetration is one of the leading causes of steel reinforcement corrosion, which can significantly reduce the durability and service life of structures.
The Rapid Chloride Permeability Test (RCPT), conducted as per ASTM C1202:2025, is a widely accepted method to evaluate the resistance of concrete to chloride ion penetration. This test measures the electrical charge passed through a concrete specimen over a six-hour period, providing an indication of its permeability.
Lower charge values indicate higher resistance to chloride ingress, which means better durability and enhanced protection of embedded reinforcement. Based on the results, concrete can be classified from high permeability to very low permeability, allowing engineers to assess quality and performance effectively.
At our accredited laboratory, RCPT is carried out under strict quality control procedures to ensure reliable and accurate results. The test plays a critical role in quality assurance for infrastructure projects, helping clients make informed decisions regarding material performance and long-term durability.
