“…Obviously, a given type of fibre can be effective only in a limited range of performance under physical (mechanical, fracture and impact) and environmental (shrinkage, freeze-thaw and durability) loadings. The benefits of combining fibres in NWC to achieve superior tensile strength and fracture toughness were recognised nearly 25 years ago by Walton and Majumdar (1975). After a long period of inactivity, there appears to be a renewed interest in hybrid FRC in recent years owing to their better performance over mono FRC.…”

An experimental study has been carried out to understand the behaviour of high-strength lightweight aggregate concrete reinforced with mono and hybrid fibres. Control, mono (single), double hybrid and triple hybrid fibre reinforced concretes were cast using macro-fibres of steel and micro-fibres of steel and polypropylene. This paper presents the segregation resistance, compressive and tensile strength, flexural toughness, stress-strain behaviour, shrinkage and water absorption of lightweight aggregate concrete C with and without hybrid fibres. The results indicate that the stability of lightweight aggregate (segregation resistance) increases when LWAC is reinforced with fibres in general and hybrid fibres in particular. Lightweight aggregate concrete with mono and hybrid fibres has shown a significant increase in tensile strength when compared with plain lightweight aggregate concrete; however, it has shown a marginal decrease in compressive strength. Lightweight aggregate concrete with mono and hybrid fibres displayed a pseudo hardening response in the post-crack region, while lightweight aggregate concrete with hybrid fibres has shown superior performance to lightweight aggregate concrete with mono fibres in terms of flexural toughness, post-crack strength and durability. The effect of water to cement ratio on the properties of lightweight aggregate concrete with hybrid fibres was also studied.

“…Düşük elastisite modülüne sahip olan lifler ise, kompozitte çatlamayı azaltarak özellikle sünekliğin artmasını sağlarlar [41]- [44]. Üstün çekme dayanımı ve kırılma tokluğu elde etmek için organik (PP, naylon) ve inorganik liflerin (cam, asbest ve karbon) birarada kullanılmasının faydaları 40 yıl önce Walton ve Majumdar [45] tarafından farkedilmiştir.…”

“…Hybrid fiber composites was first used by Walton and Majumdar (Walton, et al, 1975), they concluded that that it is possible to produce satisfactory composites by mixing organic and inorganic fibers. Using fiber with different dimensions was found to improve concrete properties.…”

Fibers are used to improve the properties of concrete. This paper investigates the mechanical properties of chopped carbon fiber-reinforced concrete (CFRC). The properties examined include workability, compressive strength, splitting tensile strength, and flexural strength. The fibers were added at the volume fractions of 0.5, 1.0, 1.5, and 2.0 percent. Adding carbon fiber to the concrete decreased the workability of concrete. Compressive strength of CFRC increases with increasing fiber content up to a certain percentage, after which increasing fiber content becomes unbeneficial. This optimum fiber content is found to be 1 percent, with strength effectiveness of 13 .65 percent. The splitting tensile strength of CFRC improved linearly with increased fiber content, and the strength effectiveness ranged from 18.37 percent to 132.6 percent. The flexural strength of CFRC improved linearly with increasing fiber content, and the strength effectiveness ranged from 3.26 percent to 13.82 percent. Relationships for compressive strength, splitting tensile strength, and flexural strength of CFRC are introduced. AbstractThis study is investigating the properties of self-consolidating concrete (SCC) containing synthetic polymer fibers. The influence of hybrid synthetic fiber reinforcement on concrete properties is reported. A total of six mixtures on which five of them are reinforced with fiber content ratio of 1 % using several percent of macro and micro fibers. The concrete mixtures' density, filling ability, passing ability, segregation and compressive strength are determined. The test results showed that all mixtures with fiber have lower density, slump and J-Ring flow than unreinforced concrete. The less the macro fiber percent in the mixture, the higher the slump flow.all mixtures are classified as resistant for static segregation resistance. SCC compressive strength decreased drastically with adding fibers linearly. homopolymer polypropylene fibers in a collated fibrillated form will give smaller flow slump, smaller compressive strength, but larger penetration depth than mixtures with homopolymer polypropylene monofilament fibers.
