BS EN 12617-3:2002 PDF Download

BS EN 12617-3:2002 is a standard that outlines the test methods for determining the early age linear shrinkage of structural bonding agents used for the protection and repair of concrete structures. This standard applies to bonding agents that are covered by EN 1501-1 and EN 1504-4. The purpose of this test method is to measure the linear shrinkage of bonding agents in the early stages, typically within the first 24 hours.

The standard provides detailed procedures for conducting the measurement of linear shrinkage. The measurements are performed on thin strips of the bonding agents, which are less than 10 mm in thickness. The tests are carried out on the bonding agents from the initial gel stage of polymerization, and the shrinkage values are recorded.
