Hygrothermal behavior of a date palm concrete
Abstract
The environmental quality of a building generally aims to take into account both the stakes of sustainable development, social and economic. For these reason, several researchers are recently interested to introduce the biobased materials for the new and renovated buildings to reduce simultaneously energy consumption, gases emission and agricultural production. Studies carried out on new biobased building materials, which contains date palm fibers (DPF), have showed their both thermal insulation efficiency and mechanical reliability. In order to characterize the behavior and the effectiveness of this material both in terms of energy saving and indoor environmental quality. We have focused our investigation on the study of the hydric behavior of DPF concrete. The buffer moisture was estimated on the outdoor environment at isothermal condition according to the NORDTEST method then at non-isothermal condition. The results showed that the DPFC could be classified as an excellent moisture and heat regulator thanks to its absorption capacity and low thermal conductivity.
