Thermal and physiochemical characterization of bricks incorporating date palm fiber for use as insulation materials in buildings

Abstract

This work presents a new compound to improve thermal comfort and decrease energy usage. The compound is composed of palm fiber, clay, and sand. The purpose of the paper is to assess the impact of combining sustainable and bio-sourced materials into bricks as heat-insulating materials, in addition to embedding the use of biocomposites in buildings. The composites were prepared by adding date palm fibers (size of 0.4 mm) with varying weight concentrations (from 0 wt% to 5 wt%). On the other hand, this biocomposite has been experimentally verified in terms of thermal and physicochemical characterization and energy economy. The TGA and DSC analyses revealed that including DPF impacted the matrix’s thermal properties. The results of FTIR and XRD indicate that fiber inclusion does not influence the chemical structure of the matrix and the non-emergence of new chemicals. This means chemical stability. SEM microscopy images also showed that palm fiber mergins do not affect the matrix. This is due to the excellent blend between palm fiber and clay, which increases the vacuum volume and porosity. Furthermore, the results showed a noticeable decrease in thermal conductivity as the palm fiber weight increased. As well as the energy economy. Hence, DPF has an excellent impact on the thermal and physicochemical properties of the biocomposite. Therefore, adding palm fiber to biocomposites enhances thermal insulation in construction.
