This work describes the distribution of the portlandite over the surface of the lime/pozzolan mortar and the mineral composition of the glassy material formed when the mortar was irradiated with continues-wave-CO2 (CW-CO2) laser.Both Micro-Raman and Raman mapping have been used for structural studies.Lime/pozzolan/sand 1/1/2 mortars, 5 years at room temperature, were irradiated with CW-CO2 laser (Synrad Firestar t80, Mukilteo, WA) operating at a wavelength of 10.591 μm, 10P(20) CO2 laser line.Laser output: 8W,18W and 38W (Synrad PW-250 (Mukilteo, WA)).The laser beam was focused by means of a NaCI lens of 10 cm focal length and the irradiation time was 5 seconds.
