This study consists in better understanding of the influence of the temperature variations on softwood morphological and structural properties. In this context, the X-ray tomography protocol has been used to follow the property variations, a specific tomographic platinum was used to generate thermal flows and to solicit the sample during scans. The...

Spruce wood, as all biosourced materials, is very sensitive to relative humidity changes, which can cause dimensional variations. In some cases, it leads to eccentricity, degradation and deterioration of the wooden structures. The 3D methods of evaluation of the spruce wood hydric behavior needs important financial resources and investigation. That...

The use of bio-based composites for building insulation is interesting from the point of view of hygrothermal performances, economic and environmental benefits. Among different organic fibers for these materials, hemp is interesting because of its huge availability in France. Nevertheless, the broad application of the hemp-based insulation mortars...

The use of hemp mortar as a bio-based insulation composite is widely promoted in the construction sector in France due to its environmental and hygrothermal advantages and the availability and low price of hemp fibers. Nevertheless, the use of such materials claims the consideration of the microbiological contamination that could lead to its degrad...

The use of the hemp concrete in the construction sector is interesting due to its hygro-thermal performances, economic and environmental benefits. Nevertheless, these performances can be affected as the hemp aggregate is a perfect substrate for a fungi proliferation. This paper focuses on the evaluation of the risk of mold contamination of the hemp...

When exposed to different building environmental conditions, bio-composite materials, such as hemp mortars, represent a risk of mold proliferation. This later plays a critical role in the biodeterioration of the materials when their physical properties are locally modified by the natural aging process. The primary objectives of the present work are...

Today, the application of various bio-based low carbon mortars leads to the use of complex multicomponent binding systems. Even if the hydration processes of the binders are known, the presence of organic particles and substances can alter the hydration kinetics and hydration rate of the mineral binder. Understanding and improving the hydration mec...

In recent years, bio-based building materials have become increasingly popular in the field of low-carbon construction. Different bio-based solutions are being adopted because of their advantageous hygrothermal properties and low economic and environmental costs. One such bio-based solution is hemp mortar, which is used in France and other countrie...

Biobased composites are widely used for building insulation because of their hygrothermal performance, and their economic and environmental benefits. Among the different types of organic fibers for these materials, hemp shives are interesting because of their high availability in France and their low price. Nevertheless, the wide application of the...
