The use of textile-reinforced concrete (TRC) in retrofit applications has proven to be an effective and viable solution. Many parameters, however, can affect the outcome, strongly inhibiting its potential. An experimental campaign was performed to assess the efficiency of TRC in strengthening reinforced concrete (RC) beams against bending with different varying parameters such as cementitious materials, number of textile layers, mechanical anchorages, and addition of short dispersed steel fibers. Results show how each parameter affects both the capacity increase and the failure mode, pointing out the beneficial effect of introducing both anchorage systems and short dispersed steel fibers.
