Abstract

The paper describes use of hemp boon as a natural organic filler for building materials, especially concrete designed as heat - insulating filler material around the load-bearing structure of wooden buildings. In constructions, hemp has been used in the form of mats made of hemp fiber, with the addition of bonding bicomponent fibers and soda solution for protection against burning and rots. Mats are formed by pneumatic fleece, they are subsequently thermally treated and then cut to the desired dimensions. Calcium-hemp building material is a revolutionary construction and thermal insulating material which can be used for building the entire building, bricks or other insulation are not necessary. The trend is spreading across Europe from France, where the mixture of boon and lime was used in the 16^th and 17^th centuries for the construction of timber-framed houses. Although there are hundreds of buildings made from hempcrete in Europe, its use in our country develops very slowly. Concrete is a mixture of hemp boon, lime hydrate, cement and water. It is a recyclable material that offers high thermal and sound insulation. The biggest advantage is undoubtedly the speed of construction, namely hemp concrete hardens very quickly.
