چکیده

Oil products can contaminate the soil in different ways. The oil pollutants are harmful contaminants that can lead to irrecoverable detriments to the environment. The petroleum pollutants not only contaminate the environmental but also, change the geotechnical properties of the soils. Therefore, it is important to investigate the geotechnical characteristic of oil-contaminated soils for engineering and environmental purposes that it is dependent on soil and contaminant type. Here, an extensive laboratory testing program was carried out to determine the effects of crude oil contamination on some of the geotechnical properties of sandy soils by Taguchi method. The results show that the compaction and uniaxial strength of the natural sand are declined due to physical and physicochemical interaction with contaminant, respectively. Aim to improve the properties of contaminated sand, the Portland cement is selected and the sand is mixed with grout according to Taguchi plan. The results show which the Portland cements can increase the unconfined strength of contaminated sand.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
