Engineering Geological and Geotechnical Investigations for Design of Oxygen Plant

“…The direct shear test result shows that the friction angle is between 19.6˚ to 33.03˚ while the cohesion, C, is between 0.25 kg/cm 2 to 0.42 kg/cm 2 , indicating strong shear resistance and a higher ability to resist the load. The bulk density values range from 1.86 g/cm 3 to 2.28 g/cm 3 , while the maximum dry density is 1.63 g/cm 3 to 1.80 g/cm 3 . The exposure of underground concrete to aggressive chemicals is negligible for sulfates and chlorides in soil and water samples that have influenced the cement selection for underground concreting.…”

“…The soil sample's bulk density values range from 1.86 g/cm 3 to 2.28 g/cm 3 , while the maximum dry density of 24 soil samples obtained from the study area ranges from 1.63 g/cm 3 to 1.80 g/cm 3 . The values obtained from the results give us an indication of durable construction [36].…”

“…Different researchers assert that to examine subsoil's geotechnical properties on the project site, it is essential to provide appropriate input data for the design and construction of foundations for the proposed buildings [2]. According to several researchers, effective design and construction of civil engineering constructions prevent negative environmental impact, structural collapse, or post-construction difficulties [3].…”

“…Recent studies have shown that the ground is often a key source of technical and financial risk in civil engineering projects [5]. Inadequate geotechnical investigations are frequently the cause of foundation problems [3]. Only adequate qualifications and accurate primary data will allow an engineer to do the task.…”
