Mechanical Characteristic of Surface Layer of Concrete with Recycled SiC

摘要

Abrasion measurement of surface of specific concrete elements is presented in this paper. This article is focus on determination of wear resistance and strength of concrete floor. This concrete contains silicon carbide binder and part of it is recycled origin. This material are high on Mohr hardness scale and are they are suitable for use in indoor and outdoor areas with the heaviest traffic loads. From the results, follows that the even small differences in mixture (using new and recycled binder) has impact on the mechanical parameters. However, it is possible design mixture with recycled binder and reach characteristic of concrete, which are almost similar to the normal concrete.
