“…Mainly because these bio-based products meet the properties and performance requirements for building materials. In addition, they are similar to commercial products and conform to regulatory specifications [5, 18, To improve the properties and/or guarantee the performance of most of the bio-based products in Table 1, studies suggest substitution percentages between 5 and 15% by weight of AWBs [6,16,18,19,21,25,33,50,51,53,66,69,77,90,100,103,115]. These findings align with a study that identified similar percentages, between 5 and 10% AWB for fired clay bricks [100].…”

“…In this same category, 24% of the studies in the period 2004 to 2021 used AWBs as a total and/or partial substitute material for conventional fine and/or coarse aggregates in concrete [21,28,29,36,66,67,83,[89][90][91][92]. A smaller percentage (3%), between 2019 and 2021, analysed the potential of AWBs as additives and/or aggregates for soil stabilisation and/or improvement of geotechnical properties [69,70,93]. Other studies used a similar classification for the categories of use of agricultural residues in concrete [15,66].…”

Background The agricultural and construction sectors demand enormous amounts of natural resources and generate environmental impacts that negatively affect ecosystems. One of the main problems is the generation and inadequate management of waste. For this reason, under the approaches of the new sustainable and circular models, waste valorization has been prioritised as a strategy for advancing towards the sustainability of production systems. This research aims to carry out a general analysis of Agricultural Waste Biomass (AWB) in the production of bio-based products for the construction sector. Bibliometric techniques were applied for the general analysis of the scientific production obtained from Scopus. A systematic review identified the main research approaches. In addition, European projects were reviewed to assess the practical application. This study is novel and provides relevant contributions to new trends in the valorisation of AWB in the building sector and the sustainability benefits. For policymakers, it is a source of information on the contribution of new policies to scientific advances and the aspects that need to be strengthened to improve sustainable and circular practices in both sectors. Results The results show that 74% of the research has been published within the last 5 years. Regarding the main types of AWBs, rice husk ash and sugar cane bagasse ash are the most commonly used in manufacturing a wide variety of bio-based building products. Cement, concrete and bricks are the main bio-based products obtained from AWB. However, a new approach to utilisation was identified in road construction. Conclusions The findings indicate that the AWB is an important resource with great potential for the construction sector. Similarly, that policies on sustainable and circular development have driven scientific progress on new alternatives for the valorisation of AWB to improve sustainability in the construction sector. Although the practical application has also been driven through European projects, development at this level is still low. Therefore, it is necessary to strengthen partnerships between these two sectors and improve government strategies on sustainability and circularity to overcome existing constraints.

“…Dumping marble dust is a difficult chore since it raises soil alkalinity and has negative effects on the human health, trees and plants, and so on. Researchers in the past investigated the use of marble dust as a soil stabilising material and discovered that it improved the geotechnical features of the soil [9,10,11,12]. It was discovered that adding fibres to clay improves its unconfined compressive strength, and that adding fiber to a clay sand mixture improves it more.…”

Due to disposal issues, waste created by various agencies poses significant danger to the environment. The purpose of this research is to use industrial wastes to stabilize the geotechnical characteristics of clayey soil, allowing the composite to be used as a sub-grade material. To make the finest subgrade material, marble dust and used polyester fiber (PF) are combined with clay soil in varied amounts. The results of the experimental testing demonstrate that stabilizing clayey soil with various waste products improves the geotechnical features of the soil, therefore reducing the waste disposal problem and keeping a healthy environment. The California bearing ratio and unconfined compressive strength are improved when these materials are used together. The mixture formed by combining marble dust with PF can be utilized as a sub-grade material, resulting in greater cost savings.

“…In addition, lime and cement are relatively expensive, causing a high increase in construction cost. Kianimehr et al [ 21 ] and Sharma and Sharma [ 22 ] reported a significant increase in the properties of improved high liquid limit soils using construction and demolition wastes and considered that recycling construction and demolition wastes into subgrade materials was a promising way to process these wastes. However, the improvement was not significant and the service life of improved soil was too short.…”

Performance Evaluation of Tunnel-Slag-Improved High Liquid Limit Soil in Subgrade: A Case Study

et al. 2022

The application of tunnel-slag-improved high liquid limit soil as filling materials in subgrade is a green environmental technology. This study explored the influence of tunnel slag mixing on the physical and mechanical properties of improved soils, based on the engineering background of Liyu highway, Guangxi Province, China. Firstly, the optimal moisture content, maximum dry density, shear strength parameters, California bearing ratio (CBR) and resilience modulus of plain and tunnel-slag-improved high liquid limit soils were experimentally determined. Results showed that the direct utilization of untreated soil was unacceptable in subgrade practice. A significant enhancement of integrity of high liquid limit soils could be obtained by tunnel slag mixing, and the value of 15% was determined as the optimal tunnel slag content in soils, leading to improved soil performance meeting the specification requirements. Then, numerical simulation on the stability of subgrade slope of tunnel-slag-improved soils at the content of 15% was conducted. It also reported the long-term subgrade settlements. The feasibility of utilization of tunnel slag in improving properties of high liquid limit soils was further validated. Finally, a good application of tunnel-slag-improved high liquid limit soil as subgrade filling materials in Liyu highway was achieved. The findings in this study could provide useful guidance for similar engineering.
