Measurement points according to RI-ZFP-TU
Meaning of german labels in the figure: Süden = south, Westen = west, Norden = north, Osten = east, Firstlinie = center of the soffit, Spur = scan
Due to the inhomogenous structure of the material concrete is difficult to test for all non-destructive methods. If accoustic methods are applied to concrete this inhomogeneity causes scattering at aggregates which complicate the interpretation of the measurement results. In order to minimize the disturbing influence of scattering Betontest performs measurements along scan paths that include the points defined by RI-ZFP-TU. By means of spatial over-sampling spatial averaging which improves the signal quality dramatically may be introduced.
