In this research a portable non-destructive technique, the external reflection infrared spectroscopy
(portable-FTIR), is compared with the traditional analytical techniques, such as powder X Ray diffraction
(XRD), optical and petrographic microscopy, scanning electron microscopy (SEM) and traditional bench
transmission FTIR. Advantages and drawbacks of this technique are here discussed, taking into account that
it was never applied systematically to mortars and cement materials
