Hygrothermal study of mortar with date palm fiber reinforcement

The present study aimsto characterize the behavior and the efficiency of a new biocomposite material based on cement mortar and reinforced with natural palm fibers both in terms of energy saving in buildings and indoor environmental quality. For this purpose, the hygric behavior of this material was investigated in terms of moisture buffer, where the material was exposed to cyclic humidity variation at isothermal conditions. The study highlights the effect of temperature and hysteresis on the moisture content within the material. The results showed that date palm fiber concrete has excellent moisture buffering capacity witha good ability for heat regulation, thanks to its moisture sorption behavior and its high thermal insulation capacity.
