Comparison of the hygric behaviour of three hemp concretes.

Written By libby furminger

Abstract:

This study compares the hygroscopic activity of three hemp concretes to determine whether composition and manufacturing impacts its hygric (moisture-related) properties. It does this by analysing thee measurement of the sorption curve, the water vapor permeability versus humidity and, the moisture buffer value.

Key Findings:

  • All materials studied were found to highly porous as well as interconnectedly porous, indicating their properties as excellent hygric regulators with high moisture transfer and storage capacities

  • Composition and manufacturing methods have a slight impact on hygric properties of hemp concrete

  • Hemp concrete’s high capacity to buffer moisture could lead to energy savings while maintaining air quality and hygrothermal comfort
