Abstract
A procedure was developed for the identification of concrete additives on the basis of their infrared transmission properties, using the new supervised classification method PRIMA (Pattern Recognition by Independent Multicategory Analysis).
The training process of identification was carried out using the IR spectral data of known additives. These data were the comparative spectral band intensities of the additives at 15 selected positions, where the absorption of the single additives showed sharp differences.
With the process elaborated identification can be carried out with 100% reliability, and this helps the prediction of expectable concrete-technological properties.
