Experimental studies of capillary phenomena in bio-based materials

Published: 5 October 2016

This project is based on the idea of promoting the use of materials and products based on forest and agricultural by-products by improving the knowledge of the moisture physical properties which affect their functionality and durability in a sustainability perspective.


Using non-destructive CT scanning in a controlled climate, capillary absorption and desorption phenomena in existing and new bio-based materials will be studied. Current knowledge is inadequate especially for some new products, such as insulating materials, but these phenomena are of crucial importance for the durability and long-term performance of bio-based products for building and living. The results of the project will be presented in an educational visualized material-property matrix based on experimental flow studies that provide a basis for material selection and constructive solutions for architects, builders and material developers.

With this project we wish to provide the basis for a continued development of bio-based materials. We do this by raising the awareness of moisture dynamics and the capillary phenomenon behind many cases of damage. The results from the project will provide the basis for the material and product development which in some cases may be necessary to justify the use of bio-based materials in harsh climates.
