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"},{"@xml:lang":"sl","#text":"Ena izmed metod karakterizacije odpornosti betonov na abrazijo je metoda ASTM C1138. Pri njej z vrtinčenjem vode in jeklenih kroglic simuliramo interakcijo med betonom in delci, ki jih nosi vodni tok. Rezultat preizkusa je povprečna obrabna globina. Metoda je uspešna pri manj odpornih betonih, medtem ko se pri betonih visoke kvalitete, kjer so obrabne globine majhne, rezultati pogosto nahajajo znotraj merilne negotovosti merjenja obrabe. Zato je kaže potreba po izboljšani natančnosti, ki jo je možno doseči z laserskim tridimenzionalnim merjenjem obrabljene površine. Poleg tega z izmero reliefa obrabljene površine tudi bolje razumemo fizikalne procese ob interakciji jeklenih kroglic s površino betona, gibanja jeklenih kroglic in sam proces abrazije"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-IRFB16O9","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-IRFB16O9"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-IRFB16O9/0c687f7c-de05-4b1f-a714-d59e316b48de/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-IRFB16O9/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-IRFB16O9"}}}}
