Durability of microfiber-reinforced mortars

Study of the performance of steel fiber reinforced concrete to water and salt freezing condition

“…Furthermore, the average pore size and most probable pore diameter of SFRC also decrease. The results are in a good agreement with what were suggested by Pigeon et al [12,14]; however, it disagree with the results reported by Yang and Zhu [15]. The pore structure parameters of SFRC increase when the content reaches to 2%, thus making the air-voids in concrete become coarser.…”

“…Incorporation of fibers into concrete is not only an effective way to improve concrete mechanical behaviors, but also durability. Pigeon et al [12,13] obtained that the use of steel and particularly carbon microfibers improves the frost and deicer salt scaling resistance of mortars. Cantin and Pigeon [14] indicated that steel fibers have no significant influence on the deicer-scaling resistance of concrete.…”

Mechanics behavior of ultra high toughness cementitious composites after freezing and thawing

“…In addition uniaxial tension tests were also performed on wet cured and freezing-thawing exposed SHFRCC specimens, and no significant drop in strain capacity was observed even after 300 cycles. Superior freezing-thawing durability of SHFRCC specimens over ordinary concrete was also reported by Ogawa et al [15] . The mechanics about frost resistance of fiber reinforced cementitious composite has been reported by prior researchers.…”

“…The mechanics about frost resistance of fiber reinforced cementitious composite has been reported by prior researchers. The research projected by Pigeon revealed that reinforcement of cementitious composites with short randomly distributed steel fibers and particularly carbon micro fibers could help to improve the frost and deicer salt scaling resistance of mortars [15] . Provided that the fibers could be appropriately dispersed into the mortars, the fiber reinforced cement-based materials could admirably withstand the expansion pressure resulted from cyclic freezing-thawing, and enhance their durable properties.…”

The Effect of Carbon Nano- and Microfibers on Strength and Residual Cumulative Strain of Mortars Subjected to Freeze-Thaw Cycles

“…Incorporation of smaller fibres could result in better crack arresting just after its initiation. Some tests on the effect of fibres on the frost durability were done by Pigeon et al (Pigeon 2002(Pigeon , 1996. They tested pastes and mortars incorporating either steel of carbon fibres.…”
