Presentation Transcript

  1. Fiber Reinforced Concrete(FRC)

  2. Feisal salah Introduction • Is a concrete mix that contains short discrete fibers, uniformly distributed and randomly oriented Aims to produce stronger and tougher concrete Can add to the tensile loading capacity of the composite system 4 types of FRC: Steel Fibers (SFRC) Glass Fibers (GFRC) Synthetic Fibers (SFRC) Natural Fibers (NFRC)

  3. Advantages • Ease of installation • Concrete placement and crack control in one operation • No requirement for crack control steel mesh • Increased cohesion of the mix • Reduced bleeding of water to the surface

  4. Disadvantages • Greater reduction of workability • High cost of the materials

  5. Steel Fiber Reinforce Concrete • Increases strain capacity and impact resistance • Improved resistance to impact and greater ductility of failure in compression, flexure and torsion • High tensile strength (0.5 – 2 GPa) • Modulus of elasticity (200 GPa) • Ductile/plastic stress-strain characteristic • Low creep

  6. Glass Fiber Reinforced Concrete • Mixed by Portland cement, fine aggregates, water and alkali-resistant glass fibers • High tensile strength (2 – 4 GPa) • Elastic modulus (70 – 80 GPa) • Brittle stress-strain characteristics (2.5 – 4.8% elongation at break) • Low creep at room temperature

  7. Synthetic Fiber Reinforced Concrete • Man-made fibers from petrochemical and textile industries • Low-volume percentage (0.1 to 0.3% by volume) • high-volume percentage (0.4 to 0.8% by volume)

  8. Selected Synthetic Fiber Types and Properties

  9. Types of Synthetic Fiber Reinforced Concrete • Acrylic • Aramid • Carbon • Nylon • Polyester • Polyethylene • Polypropylene

  10. Natural Fiber Reinforced Concrete • Obtained at low cost and low levels of energy using local manpower and technology • Unprocessed natural fibers - made with unprocessed natural fibers such as coconut coir, sisal, sugarcane bagasse, bamboo, jute, wood and vegetable • Processed natural fibers - Wood cellulose is the most frequently

  11. Typical Properties of Natural Fibers

  12. Application of FRC • Applications for new construction • Bridge • Repair and rehabilitation applications • Beam and Slab • Architectural applications • Interior Design

  13. Use of Carbon FRC as reinforcement of a concrete slab

  14. Comparison

  15. Conclusion • FRC - very costly - normally apply on bridge constructions - the ability to sustain a load without excessive deformation or failure - used as external reinforcement in the rehabilitation of reinforced concrete (RC) beams and slabs - architects used it as siding/cladding, roofing, flooring and partitions
