Prefabricerade väggelement av hampabetong

Sammanfattning: Lime Hempcrete consists of lime, water and hemp and creates an insulating, sound-absorbing, lightweight and environmentally friendly material that can be used in wall, roof and floor structures (Bevan & Woolley 2008). This construction method is not yet developed in Sweden as there has been a ban on the cultivation of the hemp plant. This ban on the cultivation of hemp was removed in 2003, when the material got a boost. You can use it in many different ways and not just in the construction industry (Ahlsten, 2010). In this study we have investigated the possibility to produce prefabricated wall elements of LHC. We have also studied its mechanical properties and dehydration time. Different types of mixes were made to find out which type of blend that worked best and had good workability properties. Four different types of wall elements were made to see how they react when they are handled and lifted and to show how you can connect the wall elements to each other and how you can connect them in corners.
