Polyvinyl alcohol fiber weakens axial compressive strength, splitting tensile strength and shear strength of concrete. ACI World Headquarters The results showed that the highest compressive strength was obtained in LWC containing 1% fiber led to an increase of about 8%. The significance of this paper lies in the characterisation of polyolefin fibre–reinforced concrete (PFRC) not only by using fracture flexural results tests but also by comparing such results with the direct tensile behaviour of the material obtained from uniaxial tests. Polyolefin fibers by having good tensile properties, abrasion resistance, and excellent resistance to chemical attacks with low cost have been propounded as an alternative to steel reinforcing meshes or steel fibers . This is the first time this synthetic fiber-reinforced concrete was used in the construction of reinforced concrete structural elements such as bridge deck and jersey barriers. 48331-3439 USA Phone: +971.4.516.3208 & 3209, Feedback via Email ASTM C 1116 Standard Specification for Fiber Reinforced Concrete and Shotcrete 2. Moreover, increasing the amount of fiber presented a growth in rupture modulus as well as splitting tensile strength. The difficulties involved in dealing with the heavyweight steel fibers during mixing is likely the reason for the less frequent use of steel fibers as opposed to the synthetic fibers. The mixture proportions used, the procedure used for mixing, transporting, placing, consolidating, finishing and curing are described. Invalid Email Address. Farmington Hills, MI “Application of high performance polypropylene fibers in concrete lining of water tunnels”, Mater Des 2014; 55: 274–9. The objective of this research was to determine the mechanical properties of polyolefin fiber reinforced lightweight concrete (LWC). This paper presents the construction of a bridge deck and jersey barriers with the newly developed polyolefin fiber reinforced concrete. The increase in the use of polyolefin fiber-reinforced concrete (PFRC) is in contrast to the limited amount of published research about its fracture behavior. One of the commonly used methods, for this purpose, is the addition of steel fibers of different geometries. Results show that discrete fibers had little effect on elastic modulus for fiber-reinforced concrete (FRC) with coarse-to-fine aggregate ratio (C/S) greater than 1.

Dubai, UAE This research work focuses on Hybrid Fibre Reinforced Concrete (HFRC) beams with polyolefin-basalt hybrid fibres. Polyolefin FRC was used for construction of a thin bridge deck overlay, a Jersey barrier, a full depth bridge deck slab, whitetopping (concrete on scarified asphalt pavement), and full depth pavement. High dosage of fiber may lead to … Polyolefin fibers were added to the reinforced composite in variable amounts (0-2%). Brandt A. The study has shown two synergies (with two fiber types that work together in the processes of fracture) and enhancement of fibers distribution and orientation on the surface of the fracture [7 M.G. Polyolefin fiber reinforced concrete also gives higher bending strength. Click here to become an online Symposium Papers subscriber. Cellulose fiber is found to enhance axial compressive strength of concrete but weakens splitting tensile strength. Hence, the main benefit of using polyolefin fiber-reinforced concrete (PFRC) lies in the excellent post-cracking behavior which, together with cost and environmental benefits, makes it an attractive alternative to conventional steel reinforcement in the construction However, a reduction in compressive strength was observed when the amount of fiber was increased. or Fibers for concrete shall be Fibermesh 650, 100 percent Such results were obtained with fibers embedded in high-performance concrete matrixes. Where Fiber-Reinforced Concrete is specified or designated on the plans, the concrete mix shall include approved polyolefin fibers. These test results show that 3M fibers improve hardened concrete material performance characteristics like steel fibers do. From the past few years, researchers have been conducting experimental studies on the beneficial aspects of polyolefin fibers in normal conventional concrete, lightweight concrete, foamed concrete, and high-performance concrete [ … 93-102, 1996. Its use enabled a reduction of the overall material cost and a total substitution of the customary steel-bar reinforcement. In this study, a real application of polyolefin fiber–reinforced concrete is reported. Hybrid fiber reinforced concrete not only increases the strength but also have influences on the crack patterns of columns. Res. The mixture proportions used, the procedure used for mixing, transporting, placing, consolidating, finishing and curing are described. The effectiveness of structural macro-synthetic polyolefin (PO) and a hybrid combination of steel and synthetic fibers on the flexural performance of glass fiber-reinforced polymer (GFRP) reinforced concrete beams is studied.
