Abstract
Lime-hemp concrete is an old insulation material, made out of hemp shiv and lime, making its way back onto the market. This thesis focuses on the usage of lime-hemp as an alternative insulation material for restoration of older wooden buildings in the town of Visby in Gotland, Sweden. The aim of this report is to investigate fire resistance properties of lime-hemp concrete and to compare it to other insulation materials in this regard. The materials compared were: lime-hemp concrete, wood fiber insulation, flax insulation, EPS (expanded polystyrene) and stone wool insulation. Two experimental tests were conducted on each material, where samples of 10x10x5 cm3 were put in a cone calorimeter and radiated for 30 minutes with heat measuring 10... (More)

The aim of this report is to investigate fire resistance properties of lime-hemp concrete and to compare it to other insulation materials in this regard. The materials compared were: lime-hemp concrete, wood fiber insulation, flax insulation, EPS (expanded polystyrene) and stone wool insulation. Two experimental tests were conducted on each material, where samples of 10x10x5 cm3 were put in a cone calorimeter and radiated for 30 minutes with heat measuring 10 and 20 kW/m2. The results showed lime-hemp having the lowest temperature profile through the material, out of the tested materials. The mass loss of the material was higher than EPS and stone wool and lower then wood fiber and flax insulation, the latter of which started burning at 20 kW/m2. Most of the mass loss is assumed to be attributed to the evaporation of water. (Less)
