Proposal of a Novel Criteria for Soil Corrosivity Evaluation and the Development of New Soil Synthetic Solutions for Laboratory Investigations

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 characteristics hence corrosivity. For experiments, an API 5L X65 pipeline carbon steel was used. presented great reliability, they seemed be adequate simulate soils with presence sulfate-reducing bacteria (SRB), chloride, high pH.
