Interactions of Water Vapor with Building Materials Measured with the
Dynamic Vapor Sorption (DVS) Technique

Date: Wednesday, 03 December 2014

Time: 11am (GMT), 45 minutes duration

Location: Online

Event type: Webinar


The evaluation of solid-vapor interactions on construction materials is important due to these materials’ sensitivity to environmental water vapour (moisture). These interactions are used as the basis of gravimetric and chromatographic characterisation techniques. This characterisations result in a better understanding of bulk and surface properties of complex solid state materials.

The interactions of water moisture with solid materials have impact over a wide range of industries and materials including pharmaceuticals, foods, fuel cell membranes and polymers. In particular to building materials, moisture sorption has significant implications for cements, woods, insulation materials and fibres.  Moisture damage is a significant factor limiting a building’s lifespan and also moisture infusion through a building’s outer structure can have a significant effect on indoor air quality and air-conditioning loads.

Dynamic Vapor Sorption (DVS) provides fundamental information, for example, about cement and concrete reaction to relative humidity changes and how this may affect its durability and shelf life. The information provided by the DVS can help then to improve these and other characteristics of cement and concrete.

Who is it for?

The seminar is targeted on staff involved in studying or understanding the stability of construction materials, like cement, concrete, asphalt and wood. They will learn how the DVS technique can be used as a powerful tool for characterizing the stability of these materials as well as using it to study other properties related to the sorption and desorption of moisture.

Presenter: Dr Jurgen Dienstmaier

Dr Jürgen Dienstmaier studied Chemistry at the Pontifical Catholic University of Peru, followed by a Master in Material Science at the Technische Universität Ilmenau in Germany. Thereafter a Ph. D. at the Ludwig-Maximilians- Universität in Munich concluded in 2013. He is currently Surface Measurement Systems Application Scientist for DVS instruments, working on various DVS research studies and applications.
