Hemp concrete is a sustainable material that becomes successful in the field of building construction. It is made out of hemp shivs mixed with a lime based binder and water and manufactured through three processes: spraying, moulding or mechanical mixing and tamping. Experiments were performed under natural and forced convection on several instrumented blocks during the curing time. The instrumentation (thermocouples, humidity sensors, weight-scales) allows investigating the drying kinetics and the moisture diffusivity and apprehending the hygrothermal behaviour of the material. It is observed that manufacturing process influences the initial water content and the final density whereas the hygrothermal behaviour depends on the material formulation.
► Experimental drying of hemp concrete under natural and forced convection.
► Temperatures, relative humidity and weight measurement.
► Estimation of the effective moisture diffusivity.
► Comparison of different setting processes, material formulations and drying modes.
