BS EN 13295:2004 PDF Download

BS EN 13295:2004 is a standard that outlines a test method for determining the resistance of products and systems used for the protection and repair of concrete structures against carbonation. The standard specifies an accelerated laboratory method for measuring the penetration of carbon dioxide through repair grouts, mortars, and concretes, without the presence of a protective coating system. It is important to note that this method does not measure the resistance to reduction in pH-value that may occur due to the absorption of other acidic gases like SO2 and HCl.

The purpose of this standard is to provide a reliable and standardized method for assessing the performance of repair products and systems in terms of their ability to resist carbonation. Carbonation refers to the process by which carbon dioxide from the atmosphere reacts with the calcium hydroxide in concrete to form calcium carbonate, leading to a reduction in the alkalinity of the concrete and the corrosion of embedded steel reinforcement.

By using this test method, manufacturers, contractors, and specifiers can determine the quality and durability of repair materials and systems, allowing them to make informed decisions regarding their use in concrete structures. The results obtained from this test can be used for quality control and assurance purposes, as well as for comparing the performance of different repair products and systems.
