Loose fill material from hemp shives and binding material for thermal insulation and structural use

Abstract

Currently building sector requires the use of new technologies and innovative materials. Realisation of mentioned requirements allow ensuring rate of performed works, reducing labor building constructions costs and improving building performance. In current work, loose fill material from hemp shives and binding material are analysed. The mixture of hemp shives and binder may be used in frame constructions as blown or poured loose fill material for thermal insulation or structural use. Hardened composite is characterised by high strength and excellent thermal conductivity when it is used in building partition and enclosures. In our work hemp shive are mineralized with different amount of liquid sodium silicate and mixed with cementitious binder. Macro- and microstructures of hardened composite are analysed, influence of amount of mineralizer on the strength and thermal conductivity of composite is evaluated.
