چکیده
Here we document the behavior at wall scale of a hemp-based hygroscopic material under various temperature and moisture dynamic conditions. The was made precast hemp concrete (HC) blocks with air cavities. It tested within bi-climatic chamber monitored thanks to hygrothermal sensors in chambers. results from an in-house heat transfer model were compared experimental data, using actual thermal hygric characteristics determined previous study. experiments allowed demonstrate how transport phenomena are coupled, particularly difference can be sufficient driving force for release moisture. work points out impact adsorption on changes wall. Finally numerical served also modelling equivalent help highlighting dumping capability bio-based material, together its insulation capacity.

Hygric Performance of a Sandstone Wall Retrofitted with Interior Thermal Insulation
Temperature, relative humidity and overhygroscopic moisture fields in a sandstone wall provided with interior thermal insulation were calculated in order to assess the hygric performance of the retrofitted wall. Computational simulations showed that during the time period of 10 years which was subject of investigation no overhygroscopic moisture appeared in the analyzed building envelope so tha...

Properties of Hemp Fibre Reinforced Concrete Composites
This research is concerned with the mechanical and physical properties of hemp fibre reinforced concrete (HFRC). An experimental program was developed based on the statistical method of fractional factors design. The variables for the experimental study were: 1) mixing method; 2) fibre content by weight; 3) aggregate size; and 4) fibre length. Their effects on the compressive and flexural perfo...
متن کاملDynamic and Static Behavior of Hollow-Core FRP-Concrete-Steel and Reinforced Concrete Bridge Columns under Vehicle Collision
This paper presents the difference in behavior between hollow-core fiber reinforced polymer-concrete-steel (HC-FCS) columns and conventional reinforced concrete (RC) columns under vehicle collision in terms of dynamic and static forces. The HC-FCS column consisted of an outer FRP tube, an inner steel tube, and a concrete shell sandwiched between the two tubes. The steel tube was hollow inside a...
