2014-9-30  In this study, FRC was made by adding each fiber to base concrete, which is corresponding to ordinary concrete. The base concrete was provided as a ready mixed concrete, and each fiber were mixed in the laboratory again for one minute by pan-type mixer (capacity: 55 l).The measured slump and air content of NC and FRC are tabulated in Table 3.In the case of PP, measured slump of FRC was

2018-2-10  Similarly, the diameter of each fiber was measured by means of a micrometer, averaging two measures taken at the two ends of the fiber itself, in accordance following the indications suggested in for round wire fibers. The fiber diameters varied between 0.10 mm and 0.45 mm, with a mean value equal to 0.25 mm and a coefficient of variation (C.o.V.) equal to 29%.

2004-9-12  A study was carried out to evaluate the use of recycled fibres from carpet industrial waste for reinforcement of concrete at 1 and 2 vol% fractions. Compressive, flexural, splitting tensile and shrinkage tests were performed. Significant increases in shatter resistance, energy absorption and

2020-3-1  PET bottles, after being disposed of, are landfilled or incinerated, leading to serious environmental problems. In this sense, the use of recycled PET as fiber reinforcement in concrete is a possible solution to overcome waste management issues (Kim et al., 2010). Major applications of recycled fibers in FRC come from the reuse of scrap tires.

2018-2-10  A fiber content of 0.46% by volume of concrete was used for the fiber reinforced concrete mixtures. The shear behaviour of the different concrete types was investigated by means of direct shear tests and the experimental results compared with those detected in different experimental campaign for similar concrete types.

2009-12-10  Introduction. Fiber-reinforced composites, today, are used in variety of applications ranging from replacements for steel reinforcement in concrete, jackets for retrofit of columns, and externally bonded reinforcement for the rehabilitation of deteriorating structural systems, to use in all composite structures such as building frames and even bridge decks. 1

For structural elements exposed to chloride environments, an important aspect of Recycled Steel Fiber Reinforced Concrete (RSFRC) durability is the corrosion resistance. In the present work, an experimental program was carried out to evaluate the long-term effects of chloride attack on the post-cracking behavior of RSFRC by performing splitting tensile tests and round panel tests.

In this experimental work, it was observed that by adding fibers in concrete is by far better than the control concrete specimen. It became obvious that 1% fiber reinforcement ratio was the optimal percentage in this study to enhance the mechanical properties of concrete. The 1% fiber reinforcement ratio threshold was also observed by [22] [23] .

The novel arrangement consists of continuous

2019-4-16  Due to the inherent property of concrete being very weak in tension, efforts have been made to overcome this deficiency by adding various type of fibers like carbon fiber reinforced polymer (CFRP), glass fiber reinforced polymer (GFRP), polypropylene fiber (PPF) and stainlesssteel fiber (SSF) smeared into the concrete mix. The present study involves experimental investigation on the use of ...

The manufacturing technology of reinforced concrete with the use of steel fibers to improve its mechanical properties is well-known and commonly used in civil engineering. Generally, steel fibers as discontinuous reinforcement of the concrete matrix are used to limit the cracking growth following the load application. Thus, the obtained concrete is characterized by an improvement of the ...
