ISO 1920-11:2013 PDF Download

ISO 1920-11:2013 is a standard that outlines the procedure for determining the chloride resistance of concrete using the unidirectional diffusion method. This test method is used to assess the penetration of chloride ions into hardened concrete samples. The standard provides a standardized approach for conducting the test, allowing for the comparison of concrete quality through comparative testing.

The test involves conditioning the concrete specimens and then subjecting them to the diffusion of chloride ions. The penetration of chloride ions into the concrete is measured over a specified period of time. This allows for the determination of the chloride penetration parameters at a given age of the concrete.

The results obtained from this test can be used to evaluate the resistance of concrete to chloride ion penetration. This information is important in assessing the durability and service life of concrete structures, particularly in environments where chloride exposure is a concern.
