Abstract:

Different kinds of fiber are used to reinforce the concrete to improve the concrete mechanical properties. The high modulus and high flexibility fibers are often used to reinforce in the cement base, which leads to the higher performance compound cement based materials. In the paper, the carbon fiber and glass fiber material are used as flexibility reinforced materials. The polypropylene fiber and the polyethylene fiber are used as strength reinforced materials. The combinations of the flexibility reinforced fiber and strength reinforced fiber are chosen as C-P HF (Carbon and Polypropylene Hyb

Abstract:

This research investigates the performance of hybrid fiber-reinforced concrete incorporating hooked-end steel fibers and coconut rope (coir fibers). The inclusion of steel fibers enhances the energy-absorbing capacity, while coir fibers contribute to delaying micro-crack formation. The study evaluates key properties such as flexural strength, residual flexural tensile strength, flexural toughness, and fiber distribution in hybrid steel-coir rope fiber-reinforced concrete. Three-point bending tests were conducted on notched beam specimens (100 × 100 × 500 mm) with a total fiber volume fraction

Abstract:

The mechanical tests of hybrid steel-polypropylene fiber-reinforced concrete (HSPFRC) have been carried out. Concretes containing different volume fraction and aspect ratio of steel and polypropylene fibers mixed in one concrete grade were critically analyzed in terms of compressive, split tensile, axial tensile properties. Test results show that the fibers, when used in a hybrid form, can result in superior mechanical performance compared to their individual fiber-reinforced concretes.

Abstract:

In Hybrid fiber reinforced concrete, hybrid fibers (steel fibers and polypropylene fibers) along with admixture like Alccofine-1203 will be used. The hybrid fiber will help to reduce the cracks due to shrinkage, creep and early age cracking along with an increase in ductility, toughness and fatigue resistance. The mineral admixture (Alccofine-1203) will help to increase the strength of concrete, modulus of elasticity along with workability, durability, and reduction in segregation. Both the mineral admixture (Alccofine) and hybrid fibers (Steel fiber and polypropylene fiber) will be beneficial

The article describes the results of experimental studies of the effect of low-modulus synthetic micro- and macro-fibers, taken separately and in combinations, on strength and durability of fiber-reinforced concrete. On the basis of the obtained data in fiber-reinforced concrete specimens testing for tension in bending, there were constructed diagrams of the deformation, according to which the influence of individual types of fibers and their combinations during hybrid reinforcement on the type of the destruction of composites was determined, the values of their power and energy characteristic

Abstract:

Concrete mixtures reinforced with a combination of steel rebar and fibers, i.e., Hybrid Reinforced Concretes (HRC), are frequently used in segmental precast tunnel linings. As massive cross-sections are usually adopted in these structures, only the minimum reinforcement is necessary to prevent the brittle failure. To study the brittle/ductile behavior of HRC tunnel segments in bending, the flexural responses of Lightly Reinforced Concrete (LRC) and that of Fiber-Reinforced Concrete (FRC) elements are modelled and combined herein. By means of this combination, the minimum reinforcement of HRC s

Abstract:

The benefits of using reinforcing fibers in latex-modified rapid-set cement preplaced concrete for emergency pavement repairs were examined in terms of strength, permeability, and durability as functions of the type of fiber. Single-type fibers, including jute, poly (vinyl alcohol) (PVA), and nylon fibers, as well as hybrid fiber mixtures prepared with two of the aforementioned fibers at a 1:1 weight ratio, were evaluated. Fibers were incorporated into the concrete mixture at 1.2 kg/m3. A vibratory press compactor that simulates roller compaction was used to increase compaction and densificati

This paper presents an experimental study on bending behavior of aramid and steel fiber reinforced concrete (AFRC and SFRC) members. The objective is to investigate effects of two types of aramid fiber and one type of steel fiber in hybrid reinforced concrete (RC) beams. The term hybrid beam is defined as the beam with fiber reinforced concrete (FRC) cast in tension zone and normal concrete (without fiber) cast in compression zone of the beam. The diameter of aramid fiber (AF) is 0.5mm and the surface condition is twist fiber consisting of two single fibers. The fiber lengths are 30mm and 40mm

Enhanced matrix packing density and tailored fiber-to-matrix interface bond properties have led to the recent development of fiber reinforced concrete with improved material tensile performance in terms of strength, ductility and energy absorption capacity. Concrete is strong in compression but weak in tension. Adding two or more type of fibers into concrete and become hybrid fiber concrete which can solve this problem. The aim of this study was to investigate the use of coconut rope to be hybrid as fiber with steel fibers. In addition, this study also analyzed the differences between hybrid f

Self-Compacting Concrete is a recently developed concept in which the ingredients of the concrete mix are proportioned in such a way that it can flow under its own weight to completely fill the formwork and passes through the congested reinforcement without segregation and self-consolidate without any mechanical vibration. Several studies in the past have revealed the usefulness of fibres to improve the structural properties of concrete like ductility, post crack resistance, energy absorption capacity etc. Fiber reinforced self-compacting concreting combines the benefits of self-compacting con

In this study, the effect of long and short steel fibers on electrical resistivity, conductivity and temperature rise of self-compacting concrete (SCC) was investigated depending on fiber combinations (single and binary hybrid) and length of the short steel fibers (6 and 13 mm). For this purpose, four mixtures were designed: non-fiber reference, a single fiber-reinforced mixture with only long fibers and two hybrid steel fiber-reinforced mixtures with long and 6mm or 13 mm short steel fiber.

Concrete is a material of high importance in infrastructure and development projects. Concrete is characterized as a brittle material. In order to minimise the brittle failure, it is beneficial to add the fibers to the concrete mix without compromising the quality of concrete. The length of polypropylene fibers (PPF) and steel fiber (SF) used in concrete mixtures are 50mmand 35mmrespectively. The aimof this paper is to learn the quality of concrete and dynamic modulus of elasticity by using Ultrasonic Pulse Velocity (UPV).

The changing cohesive stress-crack separation relationship produced by ageing of the concrete matrix is determined from the fracture test responses. An improved early-age cohesive stress response is obtained from the hybrid blend containing micro and macro fibers. The hybrid fiber blend also has a higher tensil

Concrete is poor in tensile property due to its brittle nature. Improvement in the mechanical properties of concrete is carried by combining the rebars and fibers in concrete. Earlier research state that non-metallic fibres improve pre-crack performance and metallic fibers improve post crack performance. Short fibers resist the micro-cracks at an early stage and long fibers resist macro-cracks. The combination of short and long fibers makes the performance of concrete much effective. In this study, the investigation is done on non-metallic PVA fiber with the lengths of 6mm (Short fiber) and 12
