This Irish Standard: a) establishes a protocol for assessing and determining whether a building has been damaged by concrete blocks containing excessive amounts of certain deleterious materials (aggregate containing free or unbound muscovite mica or potentially deleterious quantities of pyrite); b) describes methods for establishing the extent of the problem and categorises dwellings; c) describes the scope of any testing required and evaluation of the findings; and d) provides the Chartered Engineer with guidance on the selection of appropriate remedial works to be undertaken.
