“…200 sieve [115,118,121,123] applied to lateritic soil and black cotton soil have evidenced that the addition of sawdust ash caused a decrease in the plasticity index (PI) and MDD, while OMC and CBR increased for maximum values obtained with a 4% addition of sawdust ash; additionally complementary materials have been combined with sawdust ash to improve soil properties, like eggshell ash [116], lime [117] natural fibers of sisal [66] and Kernel palm shell ash [125], observing considerable improvement of mechanical properties of soils, increasing MDD and decreasing OMC in the case of eggshell ash, while lime increase the durability index and natural fibers decreased the MDD while the OMC and UCS increased. Other region with abundant research on the use of sawdust ash is India, where studies carried out varying percentages of sawdust ash addition, ranging from 2% and up to 25%, showed that CBR and OMC increased while MDD decreased for a clay soil from Rajouri region [93] and the expansive soil from Sitarganj region [126], but the increase of percentage addition of sawdust ash applied to Black cotton soil from Kadapa region increase the MDD value and the permeability coefficient decrease [128]; other research shows that, the addition of sawdust and coconut fiber on a kaolinitic clay from Kerala region shows that the OMC and strength of the clay increased, while a decrease in its MDD was observed; additionally, it was analyzed the effect of adding some percentages of the mixture of sawdust ash and Lime (SDAL) in an expansive black cotton soil [127], to improve compressive strength and swelling characteristics and increase its suitability use in construction, it was observed that MDD and UCS have a peak of 2% SDAL content and then decrease while the OMC decreases with an SDAL content of 1%, increases to a content of 2%, and then decreases with an increase in SDAL and CBR value increases up to 2% of SDAL and thereafter decreases; complementary research carried out adding sawdust ash and fly ash on a lateritic soil from Soraba Taluk region [129], showed that the expansion rate and plasticity index decreased and CBR increased with the percentage of addition, while the MDD increased for an addition of 10% and then decreased similar behavior to OMC that increased to an addition of 20% and then decreased. Research carried out on Tarnab soil, in Pakistan, with the addition of sawdust ash [61] and expansive clay soil of the city of Istanbul adding SDAL [99], in Turkey although research is carried out in Pakistan, showed that the liquid limit and the plastic limit decreased as the content SDAL increased; in contrast, this caused an increase in shearing strength additionally, it was observed that the permeability coefficient of the samples stabilized with SDAL in Istanbul soil was relatively higher than that of the non-stabilized samples [99] ...…”

“…In the investigations analyzed, the size of the fibers added to the soils is variable. Concerning the studies that used sawdust ash, although it has particle sizes similar to cement (less than 75m), it is observed that in some investigations the material was used as it was after calcination [9,31,96,97,117,125,128,129], while in others the material was selected and screened. through sieves of openings between 600mm and 75µm (sieve No.…”

A frequent problem in Geotechnics is the soils with inadequate physical-mechanical properties before the efforts to which they will be subjected by the constructions, incurring cost overruns caused by their engineering improvement. The need to improve the engineering properties of soils is not recent, currently observing that the most common alternatives are binders such as cement and lime. The climate change observed in recent decades and the uncontrolled emission of greenhouse gases have motivated Geotechnical and Geoenvironmental researchers to seek mechanisms for soil reinforcement from a more sustainable and environmentally friendly approach by proposing the use of recycled and waste materials. An alternative is natural fibers, which can be obtained as waste from many agro-industrial processes, implying their high availability and low cost. Sawdust as a by-product of wood processing has a rough texture that can generate high friction between the fiber and the matrix of the soils, leading to a significant increase in its shearing strength and bearing capacity. This concept of improving the properties of soils using natural fibers distributed randomly is inspired by the natural phenomenon of grass and/or plants that when growing on a slope can effectively stabilize a said slope.

“…The increase of OMC may be due to the flocculation and agglomeration of clay-sized particles because the cat-ion exchange causes increase in volume. With increase in cement content, the OMC increased as well, maybe due to the increase in fines content or to the increased amount of water required for the hydration of the cement [33,34]. The increase in OMC may be caused by the stabilizing binder requiring more moisture for the dissociation of the calcium ions and subsequent hydration process [4].…”

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.

The study investigated the effects of adding Saw Dust Ash (SDA) and Sugar Cane Bagasse Ash (SCBA) on the strength of cement with stabilized lateritic soil. The experiments carried out in both the lateritic soil and stabilized lateritic soil considered Atterberg limits, sieve/hydrometer analysis, compaction, soaked California Bearing Ratio (CBR), and Unconfined Compressive Strength (UCS) at various curing periods. Ordinary Portland Cement (OPC) was introduced into the soil with varying content (0%, 3%, 5%, 7%, and 9%) by weight of the soil sample. The results showed that CBR and UCS increased to 175.7% and 1.999 MPa, respectively, as the OPC content increased to 7%. The optimal OPC content to meet the 1.5MPa UCS requirement for road bases on low-volume sealed roads in Kenya was 7%. The next treatment involved partially replacing the OPC content with SDA and SCBA in different doses (7-0-0%, 5-1-1%, 3-2-2%, 1-3-3%, and 0-3.5-3.5%, respectively) for various curing periods. The results showed that CBR and UCS decreased as the OPC content decreased and SCBA and SDA increased. At a content of 5% OPC, 1% SDA, and 1% SCBA, UCS and CBR were 1.877 MPa and 149%, respectively, suggesting that it was the optimal dosage to meet the 1.5MPa UCS requirement for road bases on low-volume sealed roads in Kenya. The durability test indicated that the specimens treated with 5% OPC, 1% SDA, and 1% SCBA met the 80% durability index mark, as recommended for cement-stabilized soils. Previous studies used SDA and SCBA separately with cement or lime to stabilize the subgrade or subbase of roads, but this study focused on using these materials together as a partial OPC replacement to stabilize lateritic road bases for use in low-volume sealed roads. The goal was to use local agricultural and industrial waste materials in road construction and improve the strength characteristics of road bases while preserving the environment through waste utilization.
