Investigative Assessment of Concrete Slab Using Non-Destructive Evaluation Techniques
Concrete slabs are common members in building structures. Hardened concrete materials are strong in compression and relatively weak in tension and are used to withstand compressive stress in structures. Cracks in concrete occur when tensile stress exceeds the strength of concrete in tension. Significant cracks prompt the project stakeholders to question the integrity of the structure and to retain investigation teams to determine the extent of defects or distresses, identify potential causes, and assist in developing a remediation plan. Non-destructive evaluation (NDE) techniques have been gaining interests for field assessment. Properly conducted NDE shortens the time of assessment, saves cost, and provides information that is not visible to human eyes. The authors have served in many projects of structural assessment and realized the lack of knowledge on NDE techniques in the field. It is the intent of this study to discuss the advantages and limitations of NDE techniques. The projects presented include investigations of a reinforced concrete floor slab, concrete slab-on-grade system, a composite floor system, and a reinforced concrete pad foundation.
