The Dueñas Clay Formation is considered an example of a deposit lacustrine continental origin. It formed mainly by overconsolidated clays and includes feldspathic arenites, clayey silty levels; however, in geotechnical projects it clay unit treated as whole. structure each level was assessed the field, thin sections, SEM case level. In addition, identification, strength, deformation, durability...
The comparative study of the soils sample collected from Gudu and Oworoshoki area, Sokoto state Lagos State was carried out to compare index properties soil at shallow deposit. Global Positioning System (GPS) used locate coordinates site. Shallow samples (disturbed undisturbed) different depths (1m, 2m 3m) were both areas (Gudu Oworoshoki). disturbed using hand trowel, digger, hoe polythene bag...
This study investigates the effects of mucilage from Opuntia ficus-indica cladode (MOFIC), a bio-modifier, on Lime-stabilized Lateritic soil's durability and index features. Specifically, this research assessed alterations to Atterberg limits, compaction characteristics, California bearing ratio (CBR), values unconfined compressive strength (UCS) properties soil samples stabilised through labor...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
The use of dispersive soils, which are common in many parts the world, engineering applications such as water structures, earthen dams and road embankments is possible with their improvement. Recently, effects different chemicals on stabilization soils have been investigated. waste materials preferred both because more sustainable environment economic advantages it provides. silica fume (SF) a ...
Cement is proven increasing the strength of soft clays. Monmorillonite has a high shrinkage. Another hand, Kaolin small Waste material usage for stabilization agent was widely carried out this decade. BAFA (bottom ash fly ash) and POFA (palm oil fuel are rich in Silica Alumina, so they used to substitute cement. The study examined effect Monmorillonite, Kaolin, on clay with Bentonite from 4% 16...
Swelling clays characterized by their shrinkage and swelling phenomenon are known to be the main cause of cracking paved roads. So, road construction on soils require knowledge specific techniques, including chemical stabilization with lime or cement addition. This technique favors sustainable development avoiding waste production especially soils. Indeed a maximum reuse materials located in bu...
The study of geotechnical index properties soils in Oworoshoki, Kosofe, Lagos State was conducted to characterize and classify the soil samples. Disturbed undisturbed were collected at different shallow depths (1m, 2m 3m) from area laboratory test conducted. includes natural moisture content, atterberg limits (liquid limit plastic limit), particle size distribution, specific gravity, unit weigh...
Soil stabilization is the alteration of physicomechanical properties soils to meet specific engineering requirements problematic soils. Laboratory examination well recognized as appropriate for examining stabilized soils; however, they are labor-intensive, time-consuming, and expensive. In this work, four artificial intelligence based models (OMC-EM, MDD-EM, UCS-EM+, UCS-EM−) predict optimum mo...
geotechnical investigations of waste fills are rarely undertaken, and consequently the geotechnical community has little knowledge of their engineering properties. in this study, a geotechnical testing program was conducted to evaluate the engineering properties of old municipal solid waste sampled in whamyung msw landfill site, busan, korea. the conducted tests included water content, specific...
