Determination of the first-crack strength and flexural toughness of steel fiber-reinforced concrete
AbstractThe first-crack strength and flexural toughness of steel fiber-reinforced concrete specimens containing different volumes of steel fibers (0 to 1.5%) were determined using the procedures outlined in ASTM C1018, and the ASTM toughness indices were calculated. It was found that the value of the first-crack strength depended upon the sensitivity of the load versus deflection measurement system, and upon how “first crack” was defined. In addition, the shapes of the load versus deflection curves were strongly dependent on whether the deflection measuring system included or excluded the extraneous deformations (due to machine deformations and deformations at the specimen supports). It was concluded that the toughness indices depended both upon how the first-crack deflection was determined, and upon how deflections were measured. This indicates that the ASTM toughness indices are strongly influenced by the particular test procedures and methods of analysis used.
