“…To overcome the problem of swelling and shrinking, the expansive soils are either compacted or stabilized by chemicals or other stabilizers like wastes. Considering the trees that are cut across the globe, large quantities of sawdust are being generated [8][9]. Stabilizers increase workability, reduce the plasticity index and increase the strength of the soil [10,11,12,13].…”

“…According to Khan & Khan [14], about 10-13 % of the total volume of the wood log is processed into sawdust. Sawdust possesses little cementitious properties, but when blended with other materials having cementitious properties such as lime, their usage can yield better results [8,14,15]. According to Horisawa [16], dry wood consists of cellulose, lignin, hemicelluloses, and small amounts (5-10%) of other materials.…”

Subgrade strength is the main factor in determining the required thickness of any pavement. Therefore, the properties of a pavement subgrade materials must be determined, as they can predict the service life of a pavement. This paper examines the deviation of strength attained by sawdust and lime stabilized expansive soils for subgrade during different curing periods. The methodology used was conducting laboratory tests such as physical properties and mechanical property tests for both treated and untreated soil samples. In the first set-up, the soil was substituted with sawdust in the percentages of 0, 3, 5, and 7% of the dry weight of the soil, and after conducting unconfined compressive strength test, the optimum sawdust percentage obtained was 3%. The 3% sawdust was then mixed with 3% lime and 94% soil for long term tests. The sawdust-lime stabilized samples were cured for 0, 7, 14, and 28 days, and tested for unconfined compressive test and California Bearing Ratio. Based on the analysis of the results, it was concluded that a combination of 3% sawdust and 3% lime significantly improved the California Bearing Ratio and unconfined shear strength, specifically at later curing periods.

“…Experimental findings show that, in general, the addition of semi-organic or organic materials results in the decrease of workability and density of cement-based products [50]. Consequently, their mechanical properties, such as modulus of elasticity and compressive strength decrease with the increased dosage of waste content [53][54][55]. The decrease in strength with the increase in fibre content is due to the fact that fibres have a comparatively lower density, and some can appear as voids in comparison with the parent material [55].…”

Rapid urbanisation and the associated infrastructure development are creating a deficit of conventional construction materials and straining the natural resources. On the other hand, municipal solid waste (MSW) disposal poses a serious environmental problem. Landfilling of MSW is both costly and polluting. Incineration of MSW to generate energy is a commonly adopted approach. However, there are concerns associated with micro pollutants emitted from the combustion process. The carbon footprint of the process and the environmental cost–benefit balancing are disputable. There is clearly a need to adopt cost-effective alternatives to treat MSW. This paper proposes the potential application of “treated” MSW as an ingredient for construction materials. The treatment process involves placing MSW in an autoclave at 150 °C with 5 bars (0.5 MPa), followed by the separation of metals, plastics and glass for recycling purposes. The end-product, which is a semi-organic mixture (referred to as ‘biomass’), is passed through a vortex-oscillation system, which makes it more uniform as a material. Compressive testing of Portland cement-based pastes containing 10% and 15% biomass shows consistency in the results, demonstrating the potential use of biomass in construction materials.

“…Natural hair can be classified as both a natural and a waste product. The fibre of hair can be used in composites or as reinforcement to improve properties such as strength, stability, and bearing capacity, as well as reduce the formation of cracks [34]. Other natural fibres including coconut fibres are also a waste material.…”

Amazing Types, Properties, and Applications of Fibres in Construction Materials

Fibres have been used in construction materials for a very long time. Through previous research and investigations, the use of natural and synthetic fibres have shown promising results, as their presence has demonstrated significant benefits in terms of the overall physical and mechanical properties of the composite material. When comparing fibre reinforcement to traditional reinforcement, the ratio of fibre required is significantly less, making fibre reinforcement both energy and economically efficient. More recently, waste fibres have been studied for their potential as reinforcement in construction materials. The build-up of waste materials all around the world is a known issue, as landfill space is limited, and the incineration process requires considerable energy and produces unwanted emissions. The utilisation of waste fibres in construction materials can alleviate these issues and promote environmentally friendly and sustainable solutions that work in the industry. This study reviews the types, properties, and applications of different fibres used in a wide range of materials in the construction industry, including concrete, asphalt concrete, soil, earth materials, blocks and bricks, composites, and other applications.
