The Evaluation of Deterioration Condition in a Paper Mill Facility in Malaysia

抄録

This study presents a comprehensive assessment of the deterioration levels of steel and reinforced concrete columns at a paper manufacturing facility located in Malaysia. A multi-modal approach was employed, integrating non-destructive testing (NDT) techniques, specifically rebound hammer (RH) and ultrasonic pulse velocity (UPV) testing, in conjunction with visual inspection protocols to evaluate both severely deteriorated and non-deteriorated structural members. The analytical findings revealed severe corrosion and significant cross-sectional loss in specific steel columns, necessitating immediate replacement of the affected structural elements. Conversely, the reinforced concrete columns demonstrated compliance with design specifications and satisfied the structural requirements prescribed by British Standard and Eurocode. This paper proposes targeted rehabilitation and refurbishment strategies while emphasizing the critical importance of implementing preventive maintenance protocols and conducting periodic structural health monitoring to ensure long-term structural integrity and service life extension of the facility.
