Application of three-dimensional optical laser triangulation method for concrete surface morphology measurement

摘要

The proper preparation of the surface of concrete is an important stage in the construction and renovation of building structures. Before placing a concrete topping it is essential to determine the morphology of the concrete base surface. This paper describes a novel application of three-dimensional (3D) optical laser triangulation method for investigation of the concrete surface morphology. It is demonstrated that the 3D optical laser triangulation method is highly suitable for the fast exploration of large stretches of concrete base. In this paper large size concrete floors specimens with the substrate surface prepared with different roughening techniques are considered. The novel 3D scanner is used to precisely analyze the morphology of a 50 x 50 mm surface for the purposes of the nondestructive identification of the pull-off adhesion of concrete layers in layered building elements. Height parameters are used to describe the concrete surface morphology.
