Infrared and Raman Spectroscopy. Application to cementitious system
La identificación del ligante presente en un mortero u hormigón es de gran importancia a la hora de realizar trabajos de restauración. Sin embargo, son pocas las técnicas rápidas y no destructivas que permiten identificar los componentes anhidros e hidratados presentes en dichos materiales. En este curso se pretende dar una visión general sobre la utilización de técnicas espectroscópicas no destructivas aplicadas a la identificación de las fases anhidras e hidratadas del cemento con extrapolación a otros ligantes. El curso cuenta con expertos en el campo de los materiales de construcción y en el campo de la espectroscopía.
El curso de 1 día está orientado a titulados superiores con inquietudes en el campo de los materiales de construcción.
