It presents an analysis of the main provisions of the theory of concrete wear. It considers the mechanism of destruction of a material as a result of the impact of abrasive loads thereon. It justifies the importance of using steel fiber concrete in the structures experiencing dynamic, impact, abrasive loads. The article presents the methods of carrying out the research, the obtained results and the diagrams of the dependence of the steel fiber concrete strength on the consumption of steel fiber, abradability of steel fiber concrete on the consumption of steel fiber, abradability on the strength, as well as the analytical dependencies of the above-mentioned values. The obtained conclusions are based on the foregoing. The introduction of steel fiber allows us to significantly reduce the abradability of concrete (steel fiber concrete) and increase its strength. If the strength of steel fiber concrete is increased by introducing an additional amount of steel fiber, and (or) when using a higher class of concrete, the abradability is reduced. In the course of the research, the authors obtained a dependence of the change in the abradability on the strength of steel fiber concrete. |
