Recycling plant by-products: flax, rapeseed and miscanthus in construction materials
In response to the climate emergency, the construction sector is called upon to revise its practices to minimize its environmental impact. This context has encouraged the exploration of innovative and eco-friendly building materials, such as bio-based materials. These materials, often derived from plant by-products like flax, rapeseed, and miscanthus, are considered for their potential to reduce greenhouse gas emissions and energy consumption during production. Besides these environmental benefits, they also offer good performance in terms of thermal and acoustic insulation.
The research project presented aims to evaluate the integration of these by-products in the production of bio-based concrete, using low-carbon mineral binders. These innovative binders help to further reduce the carbon footprint of the concrete, in addition to the use of bio-based materials. The work involves developing different concrete formulations incorporating various rates of these by-products, in association with these ecological binders. The goal is to understand in detail how these different components influence the properties of the final concrete.
The project aims to achieve optimization of these formulations for the production of semi-dry concrete blocks or tiles, suitable for new construction applications. Ultimately, this research could lead to the creation of predictive models for the performance of these innovative concretes and a precise assessment of their environmental impact.
