Characterization of a sustainable building material made of raw earth and hemp

Master Thesis in Environmental Engineering, Technical University of Munich (TUM), Department of Civil, Geo and Environmental Engineering, Chair of Building Physics

Nadine Knößlsdorfer was a Master student from the Technische Universität München (2020-2021). She effectuated her Master project working on a preliminary study of earth-hemp composites. She investigated the use of additives such as hydrated lime and magnesium cement on the stability of earth-hemp blocks. She also carried a preliminary investigation on the environmental impact of earth-hemp materials.

Hemp-Earth Insulation: a Novel Material for Sustainable Construction

Master Thesis at the Institut für Geologie, Universität Bern, Switzerland.

Anja is a Master student at the Institut für Geologie at the University of Bern (2022-2023). She investigates the role of the drying conditions on the compressive strength of earth hemp blocks. She could use the press from the BFH Burgdorf for her experiments and plans to defend in summer 2023.

Light – earth insulation materials: Mechanical and hygrothermal properties of clay - Rapeseed (Brassica napus) and Hemp (Cannabis sativa) shives before and after accelerated aging processes.

Bachelor thesis, submitted to the Institute of Geography (GIUB), University of Bern.

Nico Renggli is a Bachelor student from the Geography department at the University of Bern (2022-2023). He works on the comparison of hemp and rapeseed shives as a building material. He also carries accelerated aging experiments through cyclic RH variations in an incubator, and thereby tests different types of earth and shives.

ICBBM2023

5th International Conference on Bio-Based Building Materials. Vienna - Austria, 21-23 June 2023.

Guilhem Douillet presented a summary of the main findings on the compressive strength of earth hemp blocks at the International Conference on Bio-based Building Materials, and could exchange with 250 experts from around the world on bio-based building materials. Together with colleagues from EMPA (Ellina Bernard), we also presented results on hemp with a binder of calcium-based cement vs a binder of magnesium-based cement.
