TRC exhibits very favorable stress–strain behavior, high Load-carrying capacity and a certain ductility which results in a strain-hardening behavior. At this paper, different Glass-TRCs were prepared using different commonly used normal and also innovative matrix compositions containing different volume fractions of micro steel fibers. Three commonly used matrices, a polymer-based composite and also a UHPC mixture were prepared containing different percentages of micro steel fibers. The direct tensile tests were applied on all specimens to study the tensile properties (first crack stress and ultimate tensile strength) and strain-hardening behavior. Considering the stress-strain curves of all specimens, it has been found that the tensile properties and strain-hardening behavior of Glass-TRC can be considerably improved by using steel micro fibers in an appropriate matrix composition.Read More
