Three-Dimensional Characterization Of Concrete’s Abrasion Resistance Using Laser Profilometry
Published 2015 · Materials Science
This paper presents development of three-dimensional characterization of concrete abrasion using the ASTM C1138 test method, which simulates underwater abrasion. To this effect, a measuring system was designed based on laser triangulation with linear illumination of the surface measured. The system allows for contactless, quick and precise measuring of average wear and other topological characteristics dependent on the type of the tested concrete. Validation results show that the system’s precision is better as conventional weighting method (<15 gram) and furthermore it allows us to analyze the spatial distribution of wear.
