Review article

The article discusses experimental studies of the strength characteristics of high-strength concrete and steel fiber reinforced concrete from highly mobile concrete and steel fiber reinforced concrete mixtures. There have been obtained experimental dependences of prism and cube strength before and after alternate cyclic freezing and thawing. Calculation formulas are proposed that demonstrate the relationship between cube and prism strength in compression and tension. Calculation diagrams of steel fiber reinforced concrete under compression and tension of experimental prism samples are formed.
