Abstract

In this study, three-dimensional (3-D) optical profilometry was used to measure the surface amplitude height parameters of the International Concrete Repair Institute's (ICRI's) nine standard concrete surface profiles (CSPs). A primary objective was to evaluate the suitability of approximating the 3-D surface (areal) parameters with those extracted from two-dimensional (2-D [linear]) profiles. Four linear profile directions were considered: two diagonals as well as parallel and transverse to the longitudinal direction of the molds. The results show that, in general, the 3-D surface parameters increase through the progression of the CSP range. Estimating the 3-D surface roughness of any CSP mold using a 2-D linear profile resulted in both underestimation and overestimation errors exceeding 50%, which demonstrates the inadequacy of 2-D linear profiles to approximate the roughness of a 3-D concrete surface. The errors were reduced considerably when using a weighted average of four linear profiles to approximate the corresponding 3-D surface parameter.
