Method for determining the parameters of surface roughness by usage of a 3D scanner

ANN modeling of pull-off adhesion of concrete layers

“…In [23][24][25], it was shown that there is a correlation between the (2D or 3D) roughness parameters and pull-off adhesion. Because of the rapid development of 3D methods [26][27][28][29][30][31][32][33][34][35][36] and an increase in the number of experimentally determinable roughness parameters, a standard regulating their number and systematizing them [37] has been developed.…”

Non-destructive and semi-destructive diagnostics of concrete structures in assessment of their durability

“…Microscopy --Geodesy -----CCTV ---Impulse response ----Impact echo ---Parallel seismic ---Ultrasonic --Ultrasonic tomography ---Acoustic emission ----Radiographic techniques ---Computer tomography ---Electromagnetic induction -----Radar techniques ---Laser static techniques -----Laser dynamic techniques -----Sclerometric static techniques ----Sclerometric dynamic techniques ----Thermographic passive techniques ----Thermographic active techniques ----Static proof loads -----Dynamic proof In recent years rapid advances in non-destructive 3D optical methods have been made. Using such methods one can obtain a 3D image of the surface of concrete [6][7][8][9][10]. Analysing the image by means of dedicated computer programs one can generate, e.g., the values of 3D roughness parameters in accordance with ISO 25178 [11].…”

Non-destructive identification of pull-off adhesion between concrete layers

“…The methodology uses parameters estimated on the concrete substrate layer surface by the latest 3D laser scanning method [37][38][39][40][41][42][43][44][45][46][47][48][49][50] and parameters estimated on the floor surface by the impulse response and impact-echo methods [51][52][53][54][55][56][57][58][59] and ANN.…”
