The article proves the efficiency of the construction-based use of fibre concrete. The technique of high-quality fine-grained fibre concrete creation is presented. The chemical composition of the binder was studied and the physical and mechanical characteristics of the filler were revealed. 2 types of steel fibers were studied: anchor and in the form of a fir-tree. The conducted studies proved the effectiveness of dispersed reinforcement with steel fiber. It is established, that the usage of fiber in the form of a fir-tree the greatest increase of operational characteristics is reached.
