Results of the Lepir 2 fire test on a hemp concrete wall at CERIB Fire Testing Centre

CERIB's Fire Testing Centre (CEF) conducted a Lepir 2* test on a hemp concrete wall on October 16, 2020, for “Construire en Chanvre” to complete the benchmarks results already acquired for this material in terms of fire behaviour.

Hemp concrete, a mixture of a mineral binder, a certified vegetable aggregate (obtained after defibration of the hemp stalk) and water, is an important discovery that dates to 1986, when the first house was renovated using hemp concrete.
