The present research focuses on the development and thermomechanical characterization of unfired solid bricks based on clay (white and red) and Timahdite sheep wool, which are local, durable, abundant, and economical materials. As this clay material is incorporated with sheep wool in the form of yarn multi-layers in opposite directions. It achieves good thermal and mechanical performance and a lightness of these bricks as acquired progress. This new method of reinforcement offers significant thermo-mechanical performance for the composite for thermal insulation in sustainable buildings. Several physicochemical analyses to characterize the raw materials were used. Thermomechanical measurements to characterize the elaborated materials. The wool yarn effect was significant on the mechanical behavior of the developed materials at 90 days, with flexural strength from 18 to 56% for the white clay. And 8–29% for the red one. Decrease in compressive strength from 9 to 36% for the white clay and 5–18% for the red one. These mechanical performances are accompanied by thermal conductivity gain ranging from 4 to 41% for the white and 6–39% for the red for wool fractions: 6–27 g. This green multi-layered bricks from abundant local materials with optimal thermo-mechanical properties, qualified for the intended use for thermal insulation and energy efficiency in the construction and development of local economies.

“…Also, the recycling of livestock waste is a great source of for sheep farming as well as environmental protection [17]. Atbir et al [2] developed a porous plaster using sheep wool as reinforcement to serve as multilayers of insulation material which enabled the study to determine the variation in the thermal and mechanical properties of the material having reduced emission of carbon monoxide when compared with other energy sources. Furthermore, thermal and mechanical of the developed composite was performed while a simulation was carried out to test the performance of the material in real-life.…”

The national decision on the neutrality of global carbon emission as well as decarbonization focus drives the need for the transformation of the building and construction sector of the economy. Thus, green building materials and its production is a better means of achieving depletion in carbon emission. More so, to achieve excellent green development in the construction industry as well as the goal of decarbonization, there is a need to investigate the emerging trends in the sustainable materials for green buildings. Hence, this study focused on the review of some of the existing green materials and its effect on the building construction. Findings from literature studies revealed six different green building materials which include bamboo, cork, straw bale, reclaimed wood, sheep’s wool and hempcrete. It was reported that each of the green material have excellent thermal insulation property, low emission of CO2 and has the ability to be recycled, thus, bringing sustainability in the circular economy as well as eco-friendliness of the material. These findings expand the scope of green materials application and can inform the government to formulate policies that will encourage sustainable green buildings.

“…Conversely, the flexural toughness of the gypsum-wool composites was significantly higher than that of the pure gypsum sample. A multilayer sheep wool-reinforced porous plaster was investigated by Atbir et al [ 22 ]. The results showed that increasing the number of wool layers led to a rise in flexural strength and a reduction in density, compressive strength, and thermal conductivity of the plaster composites studied.…”

Sheep farmers are currently facing an oversupply of wool and a lack of willing buyers. Due to low prices, sheep wool is often either dumped, burned, or sent to landfills, which are unsustainable and environmentally unfriendly practices. One potential solution is the utilization of sheep wool fibers in polymer composites. This paper focuses on the study of mechanical vibration damping properties, sound absorption, light transmission, electrical conductivity of epoxy (EP), polyurethane (PU), and polyester (PES) resins, each filled with three different concentrations of sheep wool (i.e., 0%, 3%, and 5% by weight). It can be concluded that the sheep wool content in the polymer composites significantly influenced their physical properties. The impact of light transmission through the tested sheep wool fiber-filled polymer composites on the quality of daylight in a reference room was also mathematically simulated using Wdls 5.0 software.
