Finnish university probes use of cannabis in construction
A hemp field in France
The goal is to see whether the energy efficient and eco-friendly hemp and lime-based hemp concrete could become an attractive alternative to builders, reports Yle.fi.
Researchers will investigate soundproofing and fireproof properties of the substance.
Hemp-based concrete is already marketed with names like Hempcrete and Canosmose, and is made up of a mixture of hemp fibres, lime and other materials. But current varieties of hemp-based concrete are not considered as strong as conventional concrete and are used with extra framing support.
Hemp is a relative of the cannabis plant known as marijuana, but contains a small fraction of THC, the psychoactive constituent found in marijuana.
Throughout history hemp has been used in the production of rope, fabrics, waxes, paper and other materials.
The research grant was arranged by the Regional Council of Southwest Finland, the European Regional Development Fund and the Finnish state.
