Sustainable building materials based on hemp shives and geopolymer paste

Abstract

European regulations states that the construction industry must encourage the rational and prudent use of non-renewable natural resources, as well as and increase the use of reusable resources and promote the use of renewable natural resources in production. Bio-composites based on natural aggregates such as hemp shives are widely studied and used in building sector due to their extensive properties of a range that primarily is so wide, as hempshives are increasingly combined with various binders and as their production technology is evolving rapidly. In this study three series of geopolymer paste (GP) samples were studied to obtain the most suitable binder for the production of hemp shive-based bio-composites, as well as a bio-composites were created from the most suitable binder and described their compressive strength and thermal conductivity performance.
