Abstract

The objective of this study was to determine the effect of concrete composition and moisture content on volume removal with the overarching goal to identify mechanism(s) responsible for laser scabbling. Tests under application of fixed laser parameters showed that concrete composition had a significant effect on material removal. The mechanical properties and size of coarse aggregates seemed to affect scabbling efficiency, rather than their chemical properties. The presence of pulverized fuel ash as a cement replacement material indicated to be a major factor that determines material removal volumes.
