“…S. Palaniyappan et al (2022) [31] analyzed the manufacture of bricks by alumina abrasive waste with clay in proportions 0-30% and firing at 900-1100 0 C. Eight Brick specimens were prepared with the size of 230×51× 51mm, and maximum and minimum compressive strengths of 31.15 and 19.77 were calculated. The top and minimum water absorption percentages are 10.59, and 5.84 were calculated.…”

The world is gradually looking for waste material properties and finding a way out of using it as secondary raw materials for other industrial purposes because of increasing environmental understanding and guidelines on controlling industrial waste. In the present world, the researcher’s primary aim is to enhance the usage of environmentally friendly materials and protect the environment. This research proves the possibility of using wood sawdust ash (WSDA) partially replace clay and sand manufacturing bricks. This paper used WSDA obtained from controlled combustion to replace other construction materials for bricks. The feasibility study used WSDA as an admixture with five distinct replacement levels, 5%, 10%, 15%, 20%, and 25%, for non-modular bricks (230×110×70) mm. The brick was evaluated for various strength parameters to authenticate clay bricks’ compressive strength, efflorescence, and water absorption properties. The findings revealed that the compressive strength of WSDA bricks (11.01 N/mm2) is higher than fly ash-cement-based and burnt clay bricks, which are 6.93 N/mm2 and 9.56 N/mm2. Also, the water absorption is (31%) lower than clay burnt bricks.

“…Also, the addition of binders from agricultural waste raw materials improves their structural characteristics. Therefore, in the construction of ecological buildings made of unbaked bricks, various waste raw materials from agriculture such as straw, stems, leaves, husks, etc., can be used as binders, the use of which also contributes to the reduction of harmful emissions during production of building IOP Publishing doi:10.1088/1755-1315/1234/1/012005 2 materials [8]. The need to improve thermal comfort in buildings and reduce energy consumption in buildings is one of the prerequisites for studying and improving the construction characteristics of materials used in ecological construction.…”

The production technology of the environmentally polluting baked bricks suggests that they can be replaced by bricks that are produced in an ecologically clean environment, such as the unbaked ones. In the present research work, different brick samples were made and studied, built with clay, sand and agricultural waste raw materials. With the development of the construction industry and increasing environmental requirements, research studies in the field continue to improve the thermal characteristics of the new construction materials. Thus, in the presented work bricks were made, which are a mixture of yellow clay and sand with added 5, 10, 15 and 20% wheat straw. The finished bricks are 0.35/0.08/0.17 m in size. Then, non-destructive measurements were carried out and thermal conductivity coefficient (k), specific heat capacity (Cp), thermal diffusivity (a) and density (ρ) were determined. The results of the measurements show that as the amount of wheat straw increases, the thermal characteristics of the samples improve. Finally, it is proved that the use of unbacked bricks from local clays and the utilization of binders from agricultural waste raw materials, will help to improve the energy performance of the produced environmentally friendly and economically beneficial structural building materials.

“…However, research on the potential positive impact on global warming potential (GWP) of using WS as insulation is still inadequate. Some research articles are available that discuss the potential of wood chips as a filler in bricks or as an aggregate in concrete (Alabduljabbar et al 2021, Benchouaf et al 2023. Several papers discuss clay as a plaster or a material in earth blocks (Toguyeni et al 2012, Jannat et al 2020.…”

Due to the heavy environmental impacts on the building industry, wood-based building materials are gaining interest. They may improve the indoor climate and have a low carbon footprint compared to steel and concrete structures. This study provides knowledge on the carbon footprint of wood shavings and wood shavings improved with clay as insulation materials. The study defines the lifecycle emissions of five different wall structures, of which two are of conventional type in the Finnish context and three with wood shavings as insulation. The study follows the EN standards on buildings’ life cycle assessment with a streamlined approach and discusses the applicability of the method in the normative context. The study analyzes multiple methodological aspects, including biogenic carbon, co-product allocation, and defining the functional unit in wall structure comparison. In the base case, the exterior wall using wood shaving as insulation provided the lowest GHG emissions of the compared structures. The study finds global warming potential of wood shavings moderately sensitive to allocation choices and energy sources used in the drying of wood shavings with clay, while the End-of-Life treatment option can radically change the results in biogenic global warming potential. From the perspective of applying the buildings’ life cycle assessment in the normative context, there is a call for further research for controlling uncertainties in modeling End-of-Life options of biogenic materials.
