“…However, it is practically difficult to produce a specimen by using the roller compaction method in the laboratory. Therefore, specimens were manufactured using mimic roller compaction methods, which are easy to produce specimens using existing research [15]. First, one-third of the mixed latex-modified fiber-reinforced rapid-hardening-cement concrete was poured into the test mold and vibration was conducted for 30 s using a vibration-compacting machine to apply pressure.…”

This study evaluated the effects of reinforcement fibers on the mechanical characteristics, chloride ion penetration properties and abrasion resistance of roller-compacted latex-modified fiber-reinforced rapid-hardening-cement concrete (RCLMFRRHCC) for use in the emergency repair of concrete pavements. The reinforcement fibers tested included macro synthetic fibers (a structural fiber) as well as PVA (polyvinyl alcohol) and natural Jute fibers (non-structural fibers). In the experiment, compressive strength, flexural strength, splitting tensile strength, chloride ion penetrating properties, abrasion resistance tests and impact resistance tests were performed. Test results were compared with traffic open standards of concrete for concrete pavement emergency repair. RCLMFRRHCC satisfied all traffic open standards for concrete emergency repair. Mixes with reinforcement fibers showed superior results to the mix without, in terms of compressive strength, flexural strength, splitting tensile strength, chloride ion penetration resistance, abrasion resistance and impact resistance. With regard to the reinforcement fibers, the compressive strength, flexural strength, splitting tensile strength, and impact resistance of the mix with macro synthetic fiber showed improved results as a structural fiber compared to mixes containing natural jute and PVA fibers, namely the non-structural fibers. However, using the reinforcement fiber type had little effect on chloride ion penetration resistance or abrasion resistance. Thus, the addition of reinforcement fibers was effective in improving the performance of RCLMFRRHCC. The use of macro synthetic fibers improved the mechanical characteristics of concrete.

“…us, with 28 days of curing, all mixes satisfied the target chloride ion penetration amount of ≤2000 C. Also, the target value of 4000 C or less at 4 h of curing was satisfied for all mix ratios. In the case of rapidhardening cement concretes, cracks occur inside the cement due to high hydration heat in the early stages [1][2][3]. e addition of reinforcement fibers appeared to offset hydration heat-induced crack formation [5,12].…”

“…When RCC and latex are used with rapidhardening cement for a concrete pavement, it is possible to achieve both easy construction and durability [1]. Currently, roller-compacted rapid-hardening cement concrete pavement uses up to 15% latex [1]. e use of latex up to 15% may delay the concrete's initial strength development.…”

is study evaluated the influence of reinforcement fiber type and microsilica content on the performance of latex-modified fiberreinforced roller-compacted rapid-hardening cement concrete (LMFRCRSC) for a concrete pavement emergency repair. Experimental variables were the microsilica substitution ratio (1, 2, 3, and 4%), and the reinforcement fiber (jute versus macrosynthetic fiber). In the tests, compressive, flexural, and splitting tensile strength; chloride ion penetration resistance; and abrasion resistance were assessed. From the compressive and flexural strength tests with microsilica substitution, the 4-hour curing strength decreased as the microsilica substitution ratio increased. From the chloride ion penetration test, as the microsilica substitution ratio increased, chloride ion penetration decreased. e abrasion resistances increased with the substitution ratio of microsilica increase. Based on these test results, microsilica at a substitution ratio of 3% or less and macrosynthetic fiber as the reinforcement improved the performance of LMFRCRSC for a concrete pavement emergency repair and satisfied all of the target strength requirements.
