Abstract
The aim of this study is to determine and compare surface parameters at the meso level of concrete fractured surfaces using two different laser scanning systems. One of the laser scanning systems is the cost-efficient system DAVID 3D; the other one is the high-end system LEICA T-Scan. By means of these two systems the following surface parameters were determined: the minimum distance between two points, the number of points, the roughness and the fractal dimension. A calculation routine in Matlab© was developed to estimate numerically the fractal dimension with a modified method. A major finding of this study is the suitability of the DAVID 3D system for scanning fractured concrete surfaces at the meso-level (1-100 mm). If a higher resolution is needed the LEICA system is preferable due to its ability to measure a higher number of points within a given area.
