Use of plant aggregates in building ecomaterials

摘要: The aim of this paper is to compare hemp shiv and sunflower pith properties when they are used as plant aggregates incorporated into a pozzolanic matrix. Scanning electron microscope observation these showed distinct microstructures, which could be responsible for the differences in mechanical thermal behaviour observed between composites including two types aggregates. long-term revealed mineralization aggregates, particular shiv, by calcium compounds. L’objectif de cet article est comparer les proprietes la chenevotte du chanvre et moelle tournesol dans le cadre leur valorisation en tant que granulats vegetaux associes une matrice pouzzolanique. L’observation par microscopie electronique balayage ces permis mettre evidence leurs microstructures distinctes. Ceci expliquerait ecarts comportement mecanique thermique des incorporant vegetaux.
