“…The publication [30] reported that Compression Index and Swelling Index decreased up to 27% and 31%, respectively, when the soil was mixed with 25% of limestone powder. This addition decreases the compressibility of the soil as the slope of the virgin and rebound consolidation curves are reduced.…”

The ceramic industry, which comprises with wall tiles, bricks and roof tiles, floor tiles, sanitary accessories, refractory materials and ceramic materials for domestic and other uses, is generating a huge amount of ceramic wastes. Therefore, their problem of disposal is also a great concern. This research delineates the effects of waste ceramic dust on strength and consolidation characteristics of clayey soil. Soil samples were prepared with the inclusion of various proportion of ceramic dust with clayey soil. The test results indicate that Atterberg limits, optimum moisture content, compression index and swelling index decrease due to inclusion of different percentages of ceramic dust with the studied clayey soil. On the other hand, maximum dry density and soaked California Bearing Ratio (CBR) value increase with the increase of inclusion of ceramic dust upto 20%. Further addition of ceramic dust had negative effects on these strength properties. It is recommended that ceramic dust upto 20% may be used for improving the detrimental properties of clayey soil.

“…In addition, fly ash has been shown to increase compressive strength and produce similar behavioral trends to Portland cement [11]. The use of limestone waste has been shown to reduce the swelling properties of soil, producing a more compact microstructure when examined using SEM imaging [21]. Milled brick debris has also been shown to improve the compressive strength of soils when tested using the unconfined compression test [22].…”

Desiccation cracking of cohesive soils is the development of cracks on the soil surface as a result of a reduction in the soil moisture content. The decrease in soil surface area owing to the desiccation of cohesive soils has an undesirable impact on the mechanical, hydrological, thermal, and physico-chemical properties. Many efforts have been made to improve the desiccation crack resistance of cohesive soils, but the current solutions raise a number of environmental issues, increasing the demand for sustainable soil improvement alternatives. Therefore, the main objective of this study is to investigate novel eco-friendly soil improvement techniques, such as recycled carpet fibers and a gelatin-based bioplastic, and their effect on desiccation cracking in cohesive soils. The improvement of soil crack resistance was studied by conducting desiccation cracking tests on plain and improved soils. In addition, image processing was conducted to quantitatively describe the effect of soil improvement type on the geometrical characteristics of crack patterns. Each soil improvement technique enhanced the soil strength and reduced cracking at room temperature, at an elevated temperature, and when subjecting to cyclic wetting and drying. The addition of bioplastics proved to be the most effective solution, thus demonstrating a viable option to advance future sustainable engineering practices.

“…In the same research, the carbonation effect on the treated soil was also examined. In a work published earlier, Pastor et al [22] proved the ability of limestone/calcite to improve the swelling potential of clayey soils. Lime was observed to consistently improve the soil properties examined with increased proportion.…”

Volume change in expansive soils is a problem encountered in earth work around the world. This is prominent with hydraulically bound structures or foundations subjected to prolonged moisture exposure. This behavior of clayey used as subgrade, foundation, landfill, or backfill materials causes undesirable structural functionality and failures. To prevent this happening, clayey soils are studied for possible volume change potential and degree of expansion. Consequently, the problematic soils are stabilized. In this work, the stabilization of clayey highly expansive soil classified as A-7-6 soil and highly plastic with high clay content was conducted under laboratory conditions. The treatment exercise was experimented using quicklime-activated rice husk ash (QARHA), hydrated lime-activated rice husk ash (HARHA), and calcite-activated rice husk ash (CARHA) at the rates of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, and 10%. Upon treatment with the three calcium compounds to produce three sets of treated experimental specimens, the plasticity index was observed and recorded and swelling potentials were evaluated using the plasticity index method (PIM). The results showed a consistent improvement on the properties of the treated soil with the addition of the different activated admixtures. While the utilization of CARHA and HARHA improved the clayey soil to medium expansive soil, the treated clayey soil substantially improved from highly expansive soil with a potential of 23.35% to less expansive with a final potential of 0.59% upon the addition of 10% QARHA. Finally, QARHA was adjudged as the best binding composite due to the highest rate of reduction recorded with its utilization.
