A novel method to classify the aggressiveness of soil considering its physicochemical content and development new synthetic solutions for lab uses is proposed. The results showed that main criteria existing in literature corrosivity classification might cause misunderstandings about real aggressiveness. proposed aim cover a wide range found worldwide order refine assessment their characteristic...

Near-neutral pH and a low redox potential are considered favorable conditions for immobilizing radionuclides in deep repository systems within clay formations. Cigeo is the future French Industrial Center Geological Disposal high- intermediate-level long-lived radioactive waste, to be built at depth of 500 m Callovian–Oxfordian clay. In-depth knowledge mechanisms kinetics corrosion occurring on...

Tingkah laku kakisan keluli karbon API 5L X65 dengan kehadiran bakteria penurun sulfat (SRB) dalam persekitaran CO2 adalah dikaji. Uji kaji yang dijalankan bagi meneliti tingkah ujian kehilangan berat dan analisis permukaan. Spesimen didedahkan kepada medium kawalan (tanpa konsortium bakteria) SRB selama 10 hari aliran gas berterusan. Biofilem, produk kedalaman lubang terhasil dicirikan mikrosk...

Residual stresses (RS) in pipes welded by a fully automated friction welding process, called FRIEX, are investigated using the contour method (CM) and X-ray diffraction (XRD). Samples were produced self-developed equipment, which is based on interaction between consumable intermediate rotary ring two stationary pipe sections, varying loading rate applied during of API 5L B with an X65 ring. Mec...
