Comparison of concrete toughness test standards; measurement standards in materials engineering, and the 'reproducibility' language is assay-level, a polysemy trap.
This compares concrete testing standards and measurement results, not research methods as a social or scholarly practice.
Compares engineering materials-test standards for concrete toughness; object is construction materials testing, not research.
Résumé
Abstract The major advantage of fiber-reinforced concrete (FRC) over its plain counterpart is in its improved energy absorption capability, or ‘toughness.’ There are currently several standard test methods available to characterize the toughness of fiber-reinforced concrete, but little is known of the relationship between the toughness results they produce for a given fiber-reinforced concrete. An attempt is made here to compare the results produced by three of these techniques: ASTM C 1018, ASTM C 1399, and JSCE SF-4 for the same concrete and to assess the subjectivity encountered in toughness characterization. It was found that there is no firm and reliable correlation between these three procedures; they would rank different FRCs differently. Only a weak correlation exists between the toughness parameters generated by the C 1399 and the SF-4 standards, and the correlation is highly dependent on the fiber type. The ASTM C 1018 procedure is the least reliable of all and produces Toughness Indices and RM,N values that are very difficult to interpret.
