Characterization of biosourced materials cement- date palm fibers

Abstract

The objective of this work is the use of biosourced materials in wall coverings to improve thermal insulation. This study
may contribute to the development of sustainable building and effective renovation. The natural fibers used in this work as
reinforcement are the fibers of the date palm clusters collected from Biskra (Algeria). The used matrix is cement (Portland
cement pozzolan CEM II / A-P 42.5 N) supplied by the cement company of HammaBouziane, Constantine, Algeria.
Samples prepared with four different weight fractions (0, 1, 3 and 5%) of DPF are tested after grinding. The characterization
of these samples was performed by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), differential
scanning calorimetry (DSC) and thermogravimetric analysis (TGA).
FTIR and XRD analysis show that the addition of fibers does not affect the chemical composition of the matrix. The DSC
and TGA results show that the addition of date palm fibers has an impact on the thermal properties of the matrix.
According to the obtained results, composites containing date palm fibers have in practice excellent properties that can
compete with building materials.
