“…Low-density samples tend to have higher proportions of air volume filled the voids, which serve as useful insulators. These results show the benefits of using these new insulating materials in the building sector in order to ensure thermal comfort while minimizing heating and cooling requirements [52]. These results were consistent with the works of the literatures [40][41][42][43], that reported that thermal conductivity highly influenced by porosity and bulk density.…”

The present work investigates the effect of using olive pomace bottom ash, the by-product of the clay brick industry, as an additive in the manufacture of fired clay bricks. Furthermore, it aims to improve the properties of clay bricks by using naturally available materials and also to develop an innovative way of recycling the waste resulting from the brick firing process. Olive pomace bottom ash was added to clay with multiple proportions (0%, 5%, 10%, 15%, and 20%) by weight. Bricks were molded by compression at 6.5 MPa, using a hydraulic brick press machine, and fired in an industrial scale furnace. The physicochemical, mineral, and geotechnical properties of raw materials were identified to study raw materials' effect on the final fired products' performance. The quality of fired specimens was determined by bulk density, linear shrinkage, water absorption, porosity, compressive strength, and thermal conductivity. In fact, samples with 5% olive pomace ash represent the highest compressive strength level, 11.5 MPa, compared to 9.65 MPa of reference samples. On the other hand, additions up to 20% increase the brick sample's porosity from 18.28% to 34% for the reference mixture and the brick incorporated with 20% of additive, respectively, and decrease the brick's bulk density from 1522 kg/m 3 to 1431 kg/m 3 for the reference mixture and the brick incorporated with 20% of additive, respectively. The incorporation of ash also improves the thermal conductivity of brick specimens. Expressly, thermal conductivity went from 0.41 W/m.K to 0.33 W/m.K for the reference mixture and the brick incorporated with 20% of additive, respectively, showing 37% of gain in thermal insulating properties of brick. Unfortunately, the capillary water absorption coefficient increases to 28% when 20% of additive is incorporated, which is not desired in the properties of construction materials. ASTMC67-07a standards: 2003, recommend water absorption level less than 17% for bricks with moderate weathering resistance. It was concluded that the addition of olive pomace bottom ash should not exceed 10% since it can be helpful in fired clay brick production based on standards requirements, leading to remarkable ecological gains without a loss of brick's performances.

“…Within this context, the new French RE2020 regulation [ 2 ] introduced new requirements aimed at limiting the primary energy consumption and reducing the environmental impact of building components. One of the ways to respond to this alarming observation is to use construction materials with a low environmental footprint, such as bio-based and/or geo-based materials [ 3 , 4 , 5 ].…”

This study was aimed at considering the potential of wood-based composites processed using additive manufacturing as insulators in the building sector. A polylactic acid blend with 30% wood particles was used as a feedstock material in fused filament technology. Its thermal and mechanical properties were determined for various processing conditions, including printing temperature and infill rate. The results showed a minor contraction in its tensile performance as a result of the printing process. The printing temperature had a negligible effect on its stiffness and a limited influence on the other engineering constants, such as the tensile strength and ultimate stress. The thermal properties of printed structures have been found to significantly depend on the infill rate. Although the tested 3D printed wood-PLA material exhibited good thermal properties, which were tuneable using the printing conditions, its performance was still 38% to 57% lower compared to insulators such as the glass wool of the synthetic foams used in the building sector.

“…Ouakarroucha and El Azharya [10] showed that the work of Rahim et al [11] devoted to the mixture of mortar with an amount of 16% of three vegetable fibers, namely hemp, flax and straw. The thermal conductivity of these three materials increased linearly in terms of water content, which has a remarkable effect at high temperatures.…”

The aim of this research work is to study the thermomechanical behavior of concrete with organic fibers such as camel fibers, chicken feather fibers and compare it with concrete without fibers and with synthetic fibers (polypropylene fibers). In order to study the influence of the introduction of fibers on the behavior of concretes subjected to high temperatures, tests are carried out to characterize the various physical and mechanical properties of concretes at high temperatures. Concrete formulated with different fiber content (0.5% chicken feather fiber (OCC2), 1.5% camel hair fiber (OCC3) and 0.9% polypropylene fiber (OCC4)) and ordinary concrete taken as control concrete (OCC1) are subjected to heating/cooling cycles at a rate of 1°C/min at 105°C,150°C, 250°C, 500°C and 750°C. The results showed that chicken feather fibers can be used to reinforce concrete by improving its behavior in the face of increased temperature and by having a better impact on the environment.
