Determination of Concrete Strength Used in Building Performance Analyses by Destructive and Non-Destructive Methods

Innovations and Future Pathways for Sustainable and Resilient Civil Engineering, S. Neves Lousada, Editör, igi-global, Pennsylvania, ss.107-148, 2027

Assessing the structural performance of concrete is vital for monitoring structures

and planning interventions, especially after earthquakes. Accurately determining

concrete strength ensures safety and cost- effective maintenance. Mechanical

properties such as compressive strength, elasticity, and porosity are measured by

destructive, semi- destructive, and non- destructive testing (NDT). Destructive testing

provides reliable results but can damage the structure and is costly. NDT methods

are faster and less invasive but provide estimated values. To improve accuracy, they

must be calibrated with selective destructive, semi- destructive or non- destructive

testing. Combined assessment methods, such as the SonReb (ultrasonic and rebound

hammer) method, which combines both techniques, increase reliability. Integrating

destructive and NDT approaches allows for safer, more economical assessments

and better- informed engineering decisions.
