“…e NS + limes +5% contaminated material specimen (Figure 6(c)) had some apparent cracks and fewer microholes to macroholes, while the NS + limes +20% contaminated material specimen (Figure 6(d)) had macropores (Figure 6(d)). e pores and cracks could be caused by the specimen not receiving enough moisture to achieve complete hydration [35,58].…”

“…Varying ratios of contaminated soil were used to treat the problematic soil from 0% (control) to 20% and with 6.5% of lime. e proportion of mixture ingredients selected for this experimental to estimate the role of lime and COCM in admixture stabilization of the problematic soil is based on preliminary tests to obtain the optimal result of stabilizing agents required to potentially reinforce the soil in line with the research findings of Etim et al [35] and Fattah et al ( 2014). e blended mixture response will help us envisage the impact of crude contamination in the stabilized soil samples.…”

Oil pollution causes deterioration of the physical, chemical, mechanical, and geotechnical characteristics of affected soil leading to loss of soil productivity for engineering purposes. Different stabilization methods serve as a remedy for such soil to regain its loss engineering properties. This study was concerned with the utilization of lime to stabilize crude oil contaminated soil and to investigate its efficacy for soil stabilization. The study also focused on determining the geotechnical properties of crude oil contamination and matching the result with standard specifications established for engineering works. Hydrated lime, expansive clayey soil, contaminated soil, and potable water were the materials used for the experimental investigation. The contaminated soil was treated with 6.5% lime and 0–20% crude oil contaminated materials obtained from oil exploration sites in North-Eastern Nigeria and per standard test method for laboratory evaluation of consistency limits, compaction properties, California bearing ratio (CBR), and microstructural and mineralogical assessments. The experimental results obtained were further tested statistically through one-way ANOVA and F-statistics to establish the source of variation for the geotechnical properties, while multiple linear regression and correlation statistics helped draw the connection between the consistency limits, compaction, and CBR properties of the soil-lime-COCM blend. Results indicated a coefficient of determination of 99.86. The contaminated soil materials were found to show optimal performance at a 5% ratio and 6.5% of lime for civil construction purposes.

“…The fine aggregates proportion was partially replaced with varying fractions of COCM ranging from 0-40% and using a 0.5 water cement ratio. Microstructural and mineralogical assessments were further carried out to observe the cement-COCM matrix morphology and peak intensities for chemical compositions using X-ray diffraction tests and spectrum electron microscopy respectively [54,55]. Engineers will be able to more effectively design and control problems accompanying oil-soaked contaminated concrete in a variety of engineering practices, including concrete storage tanks, machine foundations, garage floors, and oil drilling rigs, as a result of this research.…”

“…At various magnification levels, SEM is utilized for detecting deviations in morphological and structural behavior of the cured and optimally blended cement-aggregate-COCM concrete matrix. In this study, a Phenom world SEM was used to identify particles with a size of less than 100 m. High energy electrons beam pre-set at 15 kV imaging was directed on the blended test specimens to generate kinds of indicators which was exposed as SEM image fixed at 536 μm resolution and 500 × magnification [54]. The test apparatus for the experiment is presented in Fig.…”

Contaminated soil materials are often unsuitable for engineering construction works due to high content of impurities which inhibits development of mechanical strength and durability properties. This study was therefore necessary to make available empirical evidence revealing the consequences of crude petroleum pollution on the mechanical characteristics of materials made of concrete and determine its effect on civil engineering works. The study involved collection of contaminated soil sample from the Kolomani oil-well in Bauchi State, Nigeria and laboratory evaluation performed to evaluate the engineering possessions of concrete formed from contaminated soil sample. A calculated ingredient at a proportion of water to cement (W/C) set at 0.5, a mix proportion of 1:1.8:2.7 was used with the fine aggregate content replaced partially with crude oil contaminated soil materials (COCM) from 0-40%. The obtained laboratory results showed rise in compressive strength property as COCM fraction increases with the optimal response of 16.36 N/mm 2 derived at 20% replacement. The experimental results was further subjected to statistical analysis using one-way ANOVA and F-statistics to test the source of variation for the geotechnical properties. Multiple Linear Regression (MLR) and correlation statistics were then used to establish relationship between mix ratios and the geotechnical properties. The results signifies good performance with R-squared of 82.81. The benefits derived from this work would enhance production of sustainable concrete works which can be applicable in large scale for tile production.
