NMR and ultrasonic investigations of porous systems

NMR and ultrasound techniques are used for the study of the physicochemical properties of porous materials. Specifically, the properties of liquids confined in micro and nano pores such as porosity, pore size distributions, freezing point depression etc, are investigated using 1H NMR alongside standard physicochemical techniques. Ultrasonic attenuation provides information of the structural properties of the porous materials and in conjunction with 1H NMR we study the hydration mechanisms of cementitious materials.
