LITERATURE REVIEW Abstract - The goal of the current study is to investigate
how adding synthetic macrofibres, or twisted monofilament ferro fiber, to concrete affects its mechanical properties. Numerous physical and mechanical properties of concrete will be improved by the application of carefully tailored macrofiber. Throughout this inquiry, M30 grade concrete with a 0.4 water-to-cement ratio was used. Numerous strength attributes, including split tensile strength, flexural strength, and compressive strength, were investigated and documented.
Mydin M.A.O et al. (2023) [3] By experimental study of concrete specimens PTBF was provided in 0%, 0.5% up to 2.5% ratios providing concrete densities of 500,700 and 900kg/m^3 (as per British standards). Slump flow falls as it rises. in PTBF. Test results of compression, flexural and split tensile strength is found -500 and 700kg/m^3 density the optimum value is 1.5% and for 900kg/m^3 density the optimum value is 2.0%. Thus beyond 2.0% the diminished significantly. Thus, there will be reduction in air voids, thermal insulation and boost the light weight fiber concrete.
Key Words: Synthetic Macro Fiber-Twisted Monofilament Ferro Fiber (TMF Fiber), Concrete, Compressive strength, Split Tensile strength, Flexural strength.
Buratti N et al. (2011) [4] By experimental study of concrete specimen prisms/beams were casted in different ratios of same mix design (British standard). To determine the effect of fiber distribution on Flexural toughness by using 3-point bending test. Both Steel fiber and macro synthetic fiber were casted separately and combination of both in concrete. Synthetic fiber has tensile strength greater than 575MPa. Steel fiber concrete shows high strength in flexural toughness and macro synthetic fiber shows low strength in flexural toughness however, synthetic fiber increases in reduction of crack opening due to shrinkage. Thus, macro synthetic fiber is proposed for alternative to steel fiber in structural applications. Synthetic fiber is still limited.
1.INTRODUCTION While it has less resistance to tension and flexure, concrete has a stronger resistance to compression. As a result, some fractures are visible, but most are hidden because they have developed deep below the surface, inside the concrete mass. Cracks form when tensile strains are too high. Any alteration in the weather has an impact on the mechanism that causes cracking. The reinforcement holds the cracks in the concrete together as they occur. Subsequently, the weight is transferred through bond action and bar anchorage. Similar results are obtained by the use of Twisted Monofilament Ferro Fiber (TMF Fiber) reinforcement: a decrease in crack width and an increase in tensile strength. One important factor in stopping these cracks is TMF Fiber. TMF Fiber evenly holds the concrete in place and prevents cracks from forming.
A. J. Babafemi (2016) [5] By experimental investigation fiber was used at a volume of 1% throughout the conduction by considering one mix design. Diameter of fiber is 0.8mm, tensile strength-400MPa, length-40mm, elastic modulus-4GPa, aspect ratio-50. study examines the creep response of cracked reinforced concrete that has been macro synthetic fibers and mechanism responsible for creep behavior. Stress of 30%, 40%,50%, 60% about 70% of average uniaxial tensile strength(2.90MPa) is accustomed to determine uniaxial tensile creep test. Result showed tensile creep over 8 months even at stress level as low as 30% and creep fracture specimen occurred at 60 and 70% stress level. Its compressive strength is 40.19MPa. large-scale synthetic fiber is becoming increasingly preferred to steel fiber, due to light weight, resistance to corrosion and cheap in cost
1.1 Applications The main area for Twisted Monofilament Fiber (TMF Fiber) applications are as follows: 1. Highway (PQC) 2. Industrial Flooring 3. Tunnel lining 4. Airport Runway 5. Parking area 6. Canal lining 7. Nuclear power plant 8. Paver blocks and solid/Halo blocks 9. Precast concrete
