The Use of a 3D Scanner for Evaluating the Morphology of a Sandblasted Concrete Surface

The possibility of the non-destructive testing of concrete surface morphology by means of a new-generation 3D laser scanner is presented. The test results for a reference concrete substrate surface and a sandblasted concrete substrate surface are reported. The effect of sandblasting on the morphology of the concrete surfaces of the substrates is highlighted. The results are presented as three-dimensional images and the values of the morphology parameters are compared in a table.
