Thermal Properties of Plaster Reinforced with Date Palm Fibers

Abstract

This study aims both to investigate the thermal properties of plaster reinforced with date palm fibers and local natural resources valorization to batter using materials construction. For that, studying the effect of addition date palm fibers on the plaster’s thermal properties is a significant point. In this work, we measured effective thermal conductivity, thermal diffusivity, specific heat, and thermal effusivity of date palm fibers reinforced plaster has been studied by CT meter. Samples configurations with four lengths (10 mm - 40 mm) and four-weight ratios (0.5 % - 2 %) of palm fibers in plaster. The results obtained demonstrate that an increase in the fraction of date palm fiber engenders to a significant decrease in the thermal conductivity, thermal diffusivity, and effusivity, even an increase for the specific heat of different types of samples. Finally, this study is a contribution to the valorization of local materials in southern Algeria, and results encourage the use of plaster and date palm fibers in the field of construction and go to eco-friendly buildings.

Recent Progress in the Application of Coconut and Palm Oil Fibres in Cement-Based Materials

“…That is, increasing the DPF contents provides more composite capacity to absorb heat, and this feature enables the composites to be reinforced with fibres in a more insulative way than the control composite. In terms of thermal diffusivity, the results indicated that the addition of palm fibres Rachedi and Kriker [30] researched the thermal properties of plaster reinforced with DPFs. The thermal conductivity of 2% of DPF added to cementitious composite was improved by approximately 50% compared with the control specimens (Figure 41).…”

“…They also reported in their research that density is mostly related to the thermal conductivity of concrete. Rachedi and Kriker [30] researched the thermal properties of plaster reinforced with DPFs. The thermal conductivity of 2% of DPF added to cementitious composite was improved by approximately 50% compared with the control specimens (Figure 41).…”

“…Specific heat was 0.7, 0.8 and 0.9 M/m 3 K. From those literature reviews, at least 0.5% of natural fibre is needed to improve the thermal properties of cementitious materials. Reprinted from [30]. Reprinted from [30].…”

“…According to previous studies, thermal conductivity and thermal diffusivity decreased, and specific heat capacity increased by adding natural fibres. Rachedi and Kriker [30] stated that the specimens that contained 2% of DPFs resulted in 50% lower thermal conductivity than the control specimens. Fulfilling the standard requirement of mechanical strength (ACI 318) becomes difficult because it needed to incorporate a high volume of natural fibres into the mixture to improve thermal properties.…”

“…In terms of thermal properties, natural fibre reinforced cement-based materials generally exhibited good thermal properties [30] because of two reasons. Firstly, natural fibre itself has a good thermal property because of its porous structure.…”
