Research on large area surface topography measurements and a methodology for measuring
and analysing the surface topography of a concrete surface have been presented.
Two differently prepared concrete surfaces were examined. An advanced 3D scanner and
the optical (digital light projection) method have been found to be particularly useful for the
measurement of concrete surfaces.
TAS (Topography Analysis and Simulation) software has been developed for analysis of the
topography of concrete surfaces. It enables data processing, calculation of parameters, data
visualization and digital filtration.
The Ssk parameter (skewness) and bearing index Sbi were found to be useful for evaluation
of properties of the examined concrete surfaces.
Two measurement strategies: simple and fast 3D scanning and partial scanning in selected
areas corresponding to the device measurement space were applied and discussed.
The results of this research indicate that the direction towards developing a methodology
of measuring the topography of concrete surfaces is proper. Further research will focus on
a correlation between the pull-off adhesion and the concrete surface topography. Selecting the
most relevant 3D roughness parameters for concrete surfaces still remains an open issue.
