“…Compared to the unamended loess soil (w opt = 14.4% and γ d, max = 18.96 kN/m 3 ), increasing the CKD content causes a progressive increase in OMC, whereas the MDUW progressively decreased. These outcomes follow previous research findings, with these behaviours occurring due to flocculation and cementation of the soil particles by the rapid creation of C-A-H and C-S-H gels for the CKD-amended soil, and which resulted in their reduced compactibility (Peethamparan and Olek 2008;Ahmari and Zhang 2013;Naseem et al 2019;Mustafa et al 2021). The OMC increase for increasing 4 UCS test results for unamended loess soil and its mixtures with 5-20% CKD, investigating specimen curing periods of a 7 days, b 14 days and c 28 days ▸ CKD addition can be attributed to the hydraulic nature of its calcium oxide component (Baghdadi et al 1995;Miller and Azad 2000).…”

For problematic soils, conventional (cement and lime) additives can provide the necessary improvements in geomechanical properties for various infrastructure constructions. However, these additives have a high environmental impact and they are not always cost-effective, such that potential alternative additives (e.g. obtained as industrial by-products) require investigation. This paper examines cement kiln dust (CKD), obtained as a by-product of cement clinker manufacturing, for improving the geomechanical properties of an Iranian loess soil (sandy silt). Compaction, unconfined compressive strength (UCS), direct shear (DS) strength and soaking durability tests were performed on the loess soil and its mixtures with 5-20% CKD, investigating the effect of curing period (of up to 28 days) on the mobilised strength. Observations from mineralogical and microstructural examinations are also presented in this paper. Compared to the unamended loess, the strength and elastic modulus substantially increased for increasing CKD content and curing period. Improved strength and durability (under soaking) of the soil-CKD mixtures is explained by particle aggregation (of the loess soil), inclusion of the fine CKD material and the action of calcium-derived gel (linking) products. Hence, as well as reducing the disposal problem (of the CKD by product) in the cement industry, the use of this material, as additive for soil stabilisation applications, would provide an effective and sustainable option for improving the geomechanical properties, as demonstrated for the investigated loess soil.

This research mainly concentrates on eco-friendly construction material. Production of cement and concrete industries release huge amount of carbon dioxide (CO2) and greenhouse gases which affect the environment and also there is a demand in construction material by man-made or nature. The construction sector finds an economic and eco-friendly cement replacement material to achieve the demand for green concrete that improve the energy conservation and better energy saving material. In marine Bio-refinery waste produce huge quantity of calcium carbonate, whose disposal is cause of major concern. Pre-eminent solution for this problem is utilizing the marine shell waste in cement and concrete. It revises the manufacturing process to reduce the raw material usage in production and adoptable material for global warming. Therefore, the researchers focus on marine waste sea shells as the replacement material in construction industry to save the energy and also give sustainable green material. As per the previous studies by the researchers to determine the chemical composition, specific gravity, water absorption, particle size distribution of seashells and also compressive, flexural and tensile strength of concrete. It shows the seashell is filler material that slightly increases the strength when compared to the conventional materials and therefore the sea shells are suitable for the construction field to manufacture the cement and concrete with eco-friendly manner.

Soils in Saudi Arabia are emerging as potential sustainable building materials, a notion central to this study. The research is crucial for advancing construction practices in arid areas by enhancing soil thermal properties through stabilization. Focusing on Hejaz region soils, the study evaluates the impact of stabilizers such as cement, lime, and cement kiln dust (CKD) on their thermal behavior. This investigation, using two specific soil types designated as Soil A and Soil B, varied the concentration of additives from 0% to 15% over a 12-week duration. Employing a TLS-100 for thermal measurements, it was found that Soil A, with a 12.5% cement concentration, showed a significant 164.54% increase in thermal conductivity. When treated with 2.5% lime, Soil A reached a thermal conductivity of 0.555 W/(m·K), whereas Soil B exhibited a 53.00% decrease under similar lime concentration, reflecting diverse soil responses. Notably, a 15% CKD application in Soil A led to an astounding 213.55% rise in thermal conductivity, with Soil B recording an 82.7% increase. The findings emphasize the substantial influence of soil stabilization in improving the thermal characteristics of Hejaz soils, especially with cement and CKD, and, to a varying extent. This study is pivotal in identifying precise, soil-specific stabilization methods in Saudi Arabia’s Hejaz region, essential for developing sustainable engineering applications and optimizing construction materials for better thermal efficiency.
