Moisture Sorption Isotherms in Cement-based Materials

This lecture features Lars Wadso, an expert in moisture and thermal properties of materials, discussing the challenges of measuring moisture sorption isotherms in cement-based materials. Lars explains the complexities of representing sorption isotherms, the difficulties in defining physically and chemically bound water, and the different methods used to measure isotherms. He highlights the importance of understanding the moisture history, hysteresis effects, and scanning curves in interpreting the results. Lars also emphasizes the practical and scientific uses of isotherms, providing insights into the nuances of conducting accurate experiments and analyzing data.
