Study on seepage characteristics of concrete cracks based on CT 3D reconstruction and fractal theory
Abstract
• Pioneering fractal dimension characterization method based on concrete crack surfaces. • Innovative 3D permeability calculation using CT-based crack reconstruction. • Comprehensive analysis of geometric parameters reveals synergistic mechanisms governing permeability in concrete cracks. This study investigates the permeability characteristics of cracked concrete through splitting tests on C40-C70 specimens. Using 3D profilometry and X-ray CT scanning, we quantified crack morphology parameters and obtained 3D permeability measurements. Analysis of 24 crack surfaces from 12 specimens revealed that individual parameters (width, roughness, tortuosity) showed poor correlation with permeability (R ²
