Abstract (en)
[origin: WO2020136152A1] The invention relates to a test method for determining the risk potential of an alkali-silica reaction in mineral construction materials such as concrete, for example, characterized by the following steps: a) examining (220) a sample (12) by means of Raman spectroscopy for providing a structural characterization (230) of the sample (12), b) comparing (240) the examination result to values (250) stored in a database, and c) using (260) the result of the comparison (240) for ascertaining (270) a risk potential for the concrete for an alkali-silica reaction.
