“…Burning sugarcane bagasse and saw dust leads to the degradation of the air quality and the emission of harmful combustion products such as Volatile Organic Carbons (VOCs) and carbon monoxide (CO). In addition, sugarcane and fertilizer waste turn into nitrate reducing water oxygen content thus negatively impacting marine life [16][17][18][19][20][21][22][23][24]. Agricultural pollution is a main source of air and water pollution.…”

The study considers the strength and structural characterization of lateritic soil road base in order to increase the strength of low-volume sealed road construction. Sugar Cane Bagasse Ash (SCBA) and Saw Dust Ash (SDA), mixed with soil and in combination with different percentages of Ordinary Portland Cement (OPC), were utilized in the current study. Structural and mechanical characterization of the investigated samples was performed by X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD), Standard Proctor Test (SPT), Unconfined Compression Strength (UCS) Test, and California Bearing Ratio (CBR) Test. The observed increase in strength may be due to the reduction of mica, quartz, and calcite in the investigated samples. CaO and SiO2 contribute to the development of strength in cement, while SCBA, and SDA-stabilized lateritic soils. The microstructural study revealed that the mica, quartz, and calcite phases play a very important role in maintaining the strength and stability of the investigated samples.

“…Various chemical additions, including lime, cement, blast furnace slag, cement slag, coffee seed ash, agricultural waste ash, gypsum, fly ash, nano silica, silicate compounds, geopolymers, sulfonated oils, ammonium chloride, enzymes, potassium compounds, polymers, ammonium and potassium lignosulfonates, barium chloride, barium hydroxide, and bio-enzymes have been utilised to stabilise unstable soils for earthwork applications [10][11][12][13][14][15]. Soil stabilisation with chemical addition can be employed to strengthen soils with poor engineering qualities, and it can also be used for engineering purposes.…”

“…For instance, when sulphate is present, these additions may produce undesirable growth. Some of these, such as GFC soil stabiliser, ladle furnace slag, fly ash-based geopolymers, chemical stabilisers (C-A-H, C-S-H), natural and synthetic fibres, magnesium phosphate cement, jute fibre, basalt fibre, filaments, rice husks and polypropylene fibre, quick lime, lime, super absorbent polymers, geopolymers, coffee husk ash, carbonated steel, slag, phosphogypsum slag-based cementitious materials, and many more, are also being studied [6,11]. All these stabilisers were added in different dosages and most of the research works involved obtaining the optimum dosage with reference to the soil selected.…”

Soil, a naturally occurring resource, is increasingly used as a construction material. Stabilisation strengthens soil, which is weak as an engineering material. Stabilising soil changes its physical qualities, enhancing its strength. Soil stabilisation increases the shear strength and load-bearing capacity. Soil stabilisation refers to any endeavour to change natural soil for engineering purposes using physical, chemical, mechanical, or biological methods, or a mix of these. Strengthening road pavements includes improving the load-bearing capacity, tensile strength, and performance of unstable subsoils, sands, and waste materials. Due to market demands and scientific advances, the number of soil-stabilising additives has increased. These innovative stabilisers include reinforcing fibres, calcium chloride, sodium chloride, and cross-linking water-based styrene acrylic polymers, which are geopolymers that boost the load-bearing capacity and tensile strength of soil. Many materials are being explored for soil stabilisation. In this article, the authors investigated the direction of soil stabilisation research. Scientometric analysis identifies stabilisation challenges and research trends in the field. This study analysed research patterns by countries, authors, institutions, keywords, and journals from 1959 to 2023; in 2021, 150 articles were published, which was the highest number in a year. Citations peaked at 3084 in 2022. With 253 publications and 3084 citations, India was the most productive country. Iran and France published the fewest, 34 and 33, respectively. The Islamic Azad University and the National Institute of Technology had the fewest published articles with 17 articles. This work can help track soil stabilisation research and will serve as an information document for future research.

“…Many geotechnical projects aim at soil stabilization, wherein the success of soil enhancement procedures is evaluated, striving to promote soil stability, strength, resistance to erosion, and economic viability. This holds for stabilization, improvement, or reinforcement of diverse geotechnical structures [ 1 , 2 , 3 , 4 ].…”

“…When considering the use of polymers in soil stabilization, they can be categorized into three major groups: geopolymers, biopolymers, and synthetic polymers [ 5 ]. Geopolymers are inorganic substances of aluminosilicate with combinations of other elements [ 4 , 6 , 7 ]. Biopolymers are produced based on bacteria biomass and are common in nature [ 8 , 9 , 10 ].…”

The conducted investigation encompassed the comprehensive integration of mechanical, environmental, chemical, and microstructural evaluations of a composite amalgamating sandy soil and a synthetic polymer at two distinct concentrations (2.5% and 5%) across multiple curing intervals (0, 1, 2, 4, 7, 15, 30, and 45 days). The studied soil originates from an environmentally significant protected area in Brazil. The implementation of mechanisms for soil improvement in the region must adhere to technical criteria without causing environmental harm. Direct shear testing was conducted, permeability was assessed, and microstructure analysis and XRD and XRF/EDX studies of both the soil and composites were conducted. It was observed that longer curing times yielded improved results in shear stress, friction angle, and cohesive intercept, with SP_5% exhibiting the highest values compared with the soil and SP_2.5%. Adding the polymeric solution to the soil contributed to cementation and cohesion gains in the substrate. Through microstructural characterization, the polymer’s role as a cementing agent for the grains is evident, forming a film on the grains and binding them together. Based on the analyses and studies conducted in the research, it can be concluded that there is technical feasibility for applying the polymeric solution at both dosages in geotechnical projects.
