Mix design of the steel fiber reinforced concrete was analyzed based on the engineering conditions. It was indicated by comparing with the strength values of steel fiber reinforced concrete (CF40) and ordinary concrete (C40) that the tensile strength of the steel fiber reinforced concrete increased about 70%, the compressive strength increased about 10%, the initial cracking strength increased about 150%.The reasonable construction technologies were used in mixing, transportation, pouring, vibrating and curing of the steel fiber reinforced concrete in order to ensure quality of the construction.

The binary superposition mix design method is constructed to quantitatively calculate the compositions of steel fiber reinforced concrete (SFRC), which brings into sufficient cement paste wrapping steel fibers to strengthen the boundary surfaces of steel fibers with base concrete. The principle of the method is firstly introduced. The experiments were carried out to evaluate the validity of the method. In the experiment, the cubic and axial compressive strength as well as the splitting tensile strength of SFRC affected by the fraction of steel fiber by volume and the average thickness of cement paste wrapping steel fibers were tested. The results are analyzed on the basis of former studies specified in the current technical specification for fiber reinforced concrete structures, which show that the larger strengths especial the splitting tensile strength of SFRC in grade CF50 can be got by the method, but the less splitting tensile strength of SFRC in grade of CF40 should be further studied.

Splitting Tensile Test

Due to the mechanical properties related closely to the distribution of steel fibers in concrete matrix, the assessment of tensile strength of self-compacting steel fiber reinforced concrete (SFRC) is significant for the engineering application. In this paper, seven groups of self-compacting SFRC were produced with the mix proportion designed by using the steel fiber-aggregates skeleton packing test method. The hooked-end steel fibers with length of 25.1 mm, 29.8 mm and 34.8 mm were used, and the volume fraction varied from 0.4% to 1.4%. The axial tensile test of notched sectional prism specimen and the splitting tensile test of cube specimen were carried out. Results show that the axial tensile strength was higher than the splitting tensile strength for the same self-compacting SFRC, the axial tensile work and toughness was not related to the length of steel fiber. Finally, the equations for the prediction of tensile strength of self-compacting SFRC are proposed considering the fiber distribution and fiber factor, and the adaptability of splitting tensile test for self-compacting SFRC is discussed.
