In the interests of sustainable development, building materials using lignocellulosic aggregates like hemp concretes are more and more used in green construction. This type of concrete made of plant aggregates has particularly attractive thermal and hygroscopic properties. The hemp produced by agricultural holdings represents 10,000 ha in France wh...

Based on the need to reduce the carbon footprint of binders used for plant-based concretes, the development of lime–pozzolan binders is on the rise. The carbon emissions due to the binder production have to be reduced in such a way to ensure a high level of carbon storage while improving the thermal resistance of building envelopes. This paper inte...

There is a need to find alternatives to the extraction of non-renewable mineral resources for the production of new binders. Some specific building materials such as plant-aggregate-based concretes do not require high-strength binders. In this context, the lime-pozzolan technology, inherited from Roman times, can help reduce the carbon footprint of...

Fluvial sediments need to be periodically dredged from waterways. At the same time, the building sector has to find high-volume alternatives to the extraction of non-renewable mineral resources. In this context, recent research has shown the benefit of reusing calcined sediments as supplementary cementitious materials. On a different note, this stu...

The combination of lime with natural pozzolans for the production of binders in masonry construction dates back to ancient times. These were largely ignored with the industrialization of the building sector even though their use for specific applications is of interest. The use of lime-pozzolan binders with the least amount of lime is a relevant op...

Human activities require a growing need for raw materials. In order to contribute to sustainable development, many business sectors are focusing on biomass valorization. Whether from dedicated crops or first industrial processing, it generates materials with high potential that can be used in many fields. Non-food uses mainly concern the energy, ch...

In the context of global warming, the built environment offers relevant opportunities to reduce GHG emissions that underlie climate change. In particular, this can be achieved with the development of low-embodied energy building materials such as bio-based concretes. Hemp concrete has been the subject of many investigations in the field of non-load...

The return to old building methods by mixing crop by-products with mineral binders is arousing great interest in Europe since about 25 years. The use of these bio-aggregates based materials for the design of building envelopes is a valuable opportunity to deal with increasingly demanding thermal regulations. In addition, the regulatory framework is...

This book provides the tools to understand the issues related to bio-based concretes using lime as binder. Themes covered include specific properties of lignocellulosic aggregates (density, porosity, size distribution, water absorption, microstructure, soluble components under alkaline conditions), hardening of lime-based binders by carbonation an...

L’optimisation des performances énergétiques du bâtiment et la réduction des émissions de CO2 générées par le secteur de la construction sont devenus des enjeux majeurs. Il s’agit non seulement de réduire considérablement les consommations d’énergie liées au chauffage et à la climatisation durant la période de fonctionnement des bâtiments mais auss...
