“…Puppala and Pedarla [63] stressed the need of utilizing ecofriendly and economical waste materials such as bagasse ash, which offers high strength and more durability, to build subgrades over expansive soils [64][65][66][67]. ese swelling soils are also present in the Middle East and Gulf countries including Pakistan, Iran, India, Oman, and Saudi Arabia that largely affects the lightly loaded civil engineering structures [40,68]. Figure 3 shows an overview of the damage to buildings, roads, and embankments across different countries.…”

Calcium-based stabilizer materials (CSMs) exhibit pozzolanic properties which improve the properties of clayey soils by hydration, cation exchange, flocculation, pozzolanic reaction, and carbonation. In this comprehensive review, comprising over past three decades from 1990 to 2019, a mechanistic literature of expansive soil stabilization by incorporating CSMs is presented by reviewing 183 published research articles. The advantages and disadvantages of CSMs as the ground stabilizing agent are succinctly presented, and the major outcomes of physicochemical effects on soil properties are discussed in detail. After blending with CSM, the main and interaction effects on soil properties with focus on chemical processes such as X-ray fluorescence, X-ray diffraction analyses, and microstructure interaction by using scanning electron microscopy and thermogravimetric analysis have been reviewed in light of findings of past researchers. This work will help geotechnical engineers to opt for suitable CSM in the field of geoenvironmental engineering in committing to sustainable construction of civil engineering structures over expansive soils.

“…Bagasse ash is a fine residue collected from burning of bagasse fibers after crushing for sugarcane juice. Bagasse ash is a non-cohesive material having a low specific gravity and it comprises of high content of silica and since it burnt, it behaves as a pozzolanic material, thus it can be used for the stabilization of road subgrade [3], [4], [5].…”

“…The various tests are to be conducted with bagasse ash alone which in turns slightly it improves the strength of the clayey soil. The increase in strength of the combined hydrated lime-bagasse ash is higher than that of bagasse fibres employed alone [4], [5].…”

Expansive soil or clayey soil which can change its volume when the water content is available i.e., swelling and shrinkage occurs. In urban areas, borrow earth is not easily available which has to be hauled from a long distance. Quite often, large areas are covered with highly plastic and expansive soil, which is not suitable for such purpose. It results on damage of building structures and road pavements due to its low strength and high expansion. The usage of admixtures can adversely improve the soil properties, thus stabilizing the clayey soil. A critical review on various admixtures used for stabilization of expansive soil is discussed in this paper.

“…A noticeable increase in the values of UCS and CBR are observed with the addition of Bagasse ash to same soil treated with lime (Hasan et al, 2016). The soil samples used in this study (referred as black soil) were collected from Queensland, Australia.…”

“…Finally, the composite groups of lime-bagasse ash (L-BA) have been achieved at one L to three BA ratios as well as the percentage of L-BA was ranging from 6% to 25% by the dry weight of natural soil. The hydrated limebagasse ash combi- nation ratio of 1:3, considered as an appropriate combination ratio, was drawn from a number of preliminary unconfined compression strength (UCS) tests conducted on treated soil samples by changing the combination ratio of hydrated lime to bagasse ash after 28 days of curing according to Hasan et al (2016). After the addition of additives, soil samples were mixed thoroughly in order to obtain a uniform mixture.…”
