Abstract

In the COLIBRI project, the aim is to carry out work dedicated to replacing synthetic fibres with plant-based flax fibres in construction products by adopting a systemic approach to their use in plasters. The first stage of the project will involve identifying the most suitable resource for a civil engineering application and making it suitable for incorporation into plasters. Secondly, trials will be carried out to understand the fundamental scientific phenomena leading to crack reduction and to define how best to incorporate the fibres. LARIS will be involved in the third stage, which involves assessing the environmental performance of the chosen solution by applying life cycle assessment (LCA) methodology: the impacts of the materials coating+flax and coating+polypropylene will be compared. Finally, the chosen solution will be tested in an environment representative of real-life conditions.
