2020-11-1 The studied thermo-hydro-mechanical properties of hemp concrete depend on its microstructure and, mainly, the adhesion of binder/hemp shive interface. Observations with a digital microscope (Keyence) and porosity measurements showed the effect of aging on the microstructure of hemp concrete. Several cracks were found in the binder/hemp concrete ... ...
2019-12-1 Hemp concrete is known to exhibit properties of phase change materials, due to its latent heating effects, which are a result of the high heat capacity combined with the breathability and voluminous moisture handling. Fig. 8 shows the relationship between relative humidity and thermal capacity of a hempcrete wall. ...

2019-12-1 Some of the hallmark characteristics of hemp concrete are that it is carbon negative, lightweight, has a low density, excellent moisture buffer capability, low thermal conductivity, and acoustic insulation. The various properties of hemp concrete are discussed further in sub-sections below. Download : Download high-res image (920KB) ...
Hemp concrete is the most commonly used bio-based material for construction because of its hygrothermal behaviour and its contribution to reduce the environmental impacts and energy needs of buildings. Apart from these performances and environmental qualities, there is still a lack of information concerning hemp concrete durability and the evolution of its physical properties over time. ...

2021-4-30 Research for alternative binders has become a necessity due to cement’s embodied carbon, climate change, and depletion of natural resources. These binders could potentially reduce our reliance on cement as the sole binder for concrete while simultaneously enhancing the functional characteristics of concrete. Theoretically, the use of finer particles in the cement matrix densifies the pore ... ...
