Paper Abstract

In this paper, we report preliminary results of molecular structural changes in cement and concrete caused by laser radiation at 10.6 μm. One of those structural changes is the generation of glazes. At low laser powers, the glazes are small and lined up while at high powers, the glazes are bigger and randomly distributed. In the not exposed to laser radiation concrete, the Raman spectrum presents weak peaks at 200 cm-1, 550 cm-1, 700 cm-1, 750 cm-1 and 1 150 cm-1. However, these peaks are amplified by laser exposure and other peaks appear at 800 cm-1 and 1050 cm-1. The intensity of all the peaks is dependent on laser radiation power.
