“…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.…”

“…Guti é rrez et al [18] researched the influence of pozzolans on the performance of fiber-reinforced mortars and reported that, in a general manner, pozzolanic materials, particularly silica fume and metakaolin, improve the mechanical performance and durability of fiber-reinforced materials and that FA addition had a poor performance, which was associated with its low degree of pozzolanic activity. Pigeon et al [19] investigated the effects of microfibers on frost damage. The results of the freezing and thawing cycle tests and of the deicer salt scaling tests showed that the microfibers reduced the rate of deterioration due to freezing phenomena but did not completely prevent damage.…”

“…The fiber-matrix bond was adversely affected by F-T exposure. In fact, several researchers found that steel microfibers enhanced the frost resistance of concrete due to the airentraining and crack-limiting effects of fiber incorporation [19,20] . These effects of fiber reinforcement might be seen after prolonged curing, which improved the fibermatrix bond considerably.…”

Self-compacting repair mortar (SCRM) is a functional material for repair or retrofit applications. Industrial byproducts, such as fly ash (FA) or ground granulated blast furnace slag (GGBFS), can be used to reduce cement dosage and to obtain an eco-friendly material. However, these waste materials may cause durability problems at early ages as a result of curing sensitivity. In this study, the effects of high-volume FA and GGBFS replacement on early-age freeze-thaw (F-T) resistance of SCRM with and without steel microfibers were investigated. The mechanical properties, including fracture energy, were determined after F-T cycles. The fresh state properties and volume stability of the hardened specimens were studied. The results demonstrated that prolonged curing is essential to avoid the loss in mechanical properties due to F-T exposure. SCRM containing high-volume byproducts seem vulnerable to the effect of F-T at early ages, and this negative effect cannot be overcome with steel microfibers.

“…The addition of carbon and stainless steel fibers also has beneficial mechanical characteristics, including improvement of tensile and flexural strength [5], reduction of shrinkage during drying [6], and the ability to better withstand frost damage [7] from freeze-thaw cycling.…”

The term Intelligent Highway is usually intended to mean external systems that are added to pre-existing highways. However, the ability to construct basic passive electronic elements is demonstrated employing electrically dissimilar Portland cement pastes. These electronic elements include resistors, rectifying pn-junctions, piezoelectric and piezoresistive sensors, and thermocouple junctions. It may therefore be possible to build intelligence into the highway itself utilizing cement-based electronic devices. As compared to semiconductor-based electronic components, those derived from cement have minimal materials and processing costs, do not require clean rooms, and are mechanically more rugged. Results and characterizations are presented for resistive elements and rectifying pn-junctions derived from admixtures of stainless steel fiber (n-type) and carbon fiber (p-type) in Portland cement. These elements are then combined to produce a monolithic cement-based digital logic 2-input AND gate.
