“…The specific gravity of the clay soil is 2.58 and is classified as inorganic soils because it's within the range of specific gravity for clay minerals (2.44 to 2.92) as reported by [27]. However, the specific gravity of calcium carbide waste (1.78) is less than the specific gravity of the clay soil [28].…”

Problematic subgrade soil such as clay is expansive by nature and is challenging to work with during pavement construction. In an effort to combat this issue and lower the rate of pavement failure on highway construction projects, cementitious industrial waste materials should be used. This study thus examined the influence of steel slag (SS) and calcium carbide waste (CCW) as stabilisers for clay soil. Chemical and mineralogical analyses of clay soil, SS and CCW were assessed while the stabilised soil were subjugated to Atterberg limit, compaction and california bearing ratio (CBR) tests. The existence of calcium oxide, iron oxide and calcium hydroxide in both the chemical and mineralogical constituents of SS and CCW indicate that they are binding materials which notably influences hardness and contributes more to the strength of the clay soil. With varied amounts of the additives (SS and CCR), the clay soil's liquid limit and plasticity index dropped from 54.0% and 13.8% to 43.5% and 9.2%, respectively. This significantly lowers the clay soil’s swell potential, increases its resilience, and decreases its infiltration capacity. The compaction characteristics revealed that SS and CCW enhanced the compactness of the clay soil signifying enhancement of the soil compaction properties. The CBR value of all the stabilised clay soils improve significantly with 40%SS + 60%CCW acquiring the maximum CBR of 17.3% and 29.0% compared with clay soil having CBR of 4.7% and 6.9% in soaked and unsoaked states respectively.

“…The interdependence between stabilized soil microstructure and strength development has been studied insufficiently because, generally, engineering tests have been applied to determine improvement effect. Scanning electron microscopy (SEM) has been effectively applied to study the stabilization effect (Angelova and Evstatiev, 1990;Nontananandh et al, 2005;Kamruzzaman et al, 2006;Antonov, 2013;Romero, 2013;Ural, 2021, Quadri et al, 2022.…”

Zeolite and Portland cement have been used to stabilize a loess soil from the region of Kozloduy (North Bulgaria). This paper examines the microstructural behavior of cement–zeolite treated loess soil without compaction at water content higher than optimum. Scanning electron microscopy and semi-quantitative energy dispersive spectroscopy analyses on stabilized loess were carried out after various curing periods. The identification of the formation of cementitious products in treated loess soil was conducted by SEM–EDS spectral analysis. Based on the study of the microstructural development, it was found that the modified loess microstructure undergoes significant modifications during the observed period.
