RESEARCHING ABRASION OF STEEL FIBER CONCRETE

Abstract

The use of monolithic steel fiber concrete in construction and in production of monolithic and prefabricated building structures allows significantly reducing complexity of reinforcement operations, as well as reduces duration of work. Dispersed distribution of steel fiber in the concrete matrix  allows the material to successfully resist both compression and tension throughout the volume

of the material. Therefore, steel fiber reinforced concrete is recommended to be used in structural elements that are working mainly on dynamic and impact loading, wrinkling, or cavitation. A number of structures, in which steel fiber reinforced concrete is widely used, experience such loads as abrasion or wear. The article regards the problem of abrasion (wear resistance) of steel fiber concrete. Methodology of the research and obtained results are presented together with graphs of dependency of steel fiber reinforced concrete’s strength on the consumption of steel fibers, steel fiber concrete’s abrasion on consumption of steel fibers, abrasion on strength, as well as analytical dependencies of the abovementioned values. The obtained results are analyzed. On the basis of the above mentioned, a summary is presented in conclusion. Implementation of steel fiber allows for a significantly reduction of concrete (steel fiber concrete) abrasion and enhance its strength. In the course of research, a dependency of the change in abrasion on the strength of steel fiber concrete is obtained.
