Introduction of FRP Bar

FRP bar

TAPASHRI Engineering (FRP bar) belongs to the class of fibrous composite material. One of the most famous composite materials is a reinforcing fiberglass rod (reinforcement), which is used in many areas of marine, industrial and civil construction.

TAPASHRI reinforcement demonstrates its best qualities in construction areas, where high-strength, corrosion-free, durable, non-metallic reinforcement is required. The rods are made by the method of pultrusion - the method of pulling. Tapashri have a uniqueness in rib geometry allows for high adhesion to concrete.

COST- EFFECTIVE ALMOST 30 TO 40%

  • Compare to TMT Bar, FRP bar is cheaper

CORROSION FREE

  • Flexible joints made of composite materials do not corrode, thus increase in operational life

LONG LIFE ALMOST 100 YEARS

  • Resistance to a variety of mechanical damages.

LIGHT Weight APPROX 3 TO 4 TIMES

  • In contrast to metal analogues; composite joints do not make walls heavy.

EASY INSTALLATION

  • Experts note that fiberglass joints are very easy to mount.

DIELECTRIC AND DIAMAGNETIC

  • Flexible joints can properly unite the inner part of a wall, thermal isolation and exterior part into a unique and strong construction. Due to their unique characteristics composite materials are the best for production of flexible joints.

ENERGY EFFICIENT

  • Fiberglass flexible joints increase the level of thermal efficiency of a building by 35%

One such product is a “Composite Rebar” which has potential to replace the traditional steel reinforcement in construction materials. The GFRP rebar are made with glass fiber and other chemical compound bound together with our own developed manufacturing technology

The main advantages are:

  • Good in Tensile Strength - (Tensile strength is more than double to steel rebar)
  • Very light in weight
  • Reduce Cost in Compare to Steel
  • Improve Life of structure
  • Corrosion Free Material - Resistant to corrosion, alkalis, acids
  • Available in Any Length so, we avoid lapping - Simpler and more economic to transport (Round coils)
  • Material Characteristics is very good in compare to Metallic Reinforcement -Minimization of repair work and increases durability of the reinforced construction design

The disadvantage is:

  • We do not Bend FRP Bars at onsite (In Current situation)

report and recommendation

Govt. Guidelines

Government bodies and also the private construction companies have started recognizing the benefits of these technology and started using this product in various applications.

Recently even Honorable Cabinet Minister of MoRTH Shri Nitin Gadkari and Shri Sanjay Kumar Nirmal (Secretary General – IRC) has promoted the use of composite rebars in national highway and bridges construction

  • Issued the Guidelines on use of Fiber Reinforced polymer (FRP) bars in Road Projects
    Ref: IRC:137-2022 “Guidelines on use of Fiber-Reinforced Polymer Bars in Road Projects (Part 1 : Glass Fiber reinforced Polymer Bars
  • Honorable Cabinet Minister of MoRTH Shri Nitin Gadkari, Clearly inform that now we are using FRP bars at new road and building development work.
    Ref: “INDIA Will Get innovative "Glass Fiber Steel" Technology - Nitin Gadkari Saheb https://www.youtube.com/watch?v=pbGEqpjBNmw”
  • Within a Month we received the Indian Standard Solid Round Glass Fiber Reinforced Polymer (GFRP) Bars for Concrete Reinforcement
    Ref: Doc No. CED 54 (19165)WC; Draft Title: Draft Indian Standard Solid Round Glass Fiber Reinforced Polymer (GFRP) Bars for Concrete Reinforcement — Specification (ICS No. 83.140.30, 93.030)

Indian Standard code: 18256:2023

IS Code 18256 (2023):

Solid Round Glass Fibre Reinforced Polymer (GFRP) Bars for Concrete Reinforcement

This Indian Standard was adopted by the Bureau of Indian Standards, after the draft finalized by the Concrete Reinforcement Sectional Committee had been approved by the Civil Engineering Division Council.

This standard has been formulated to cover requirements for glass fibre reinforced polymer (GFRP) bars for concrete reinforcement. GFRP bars are used across the world as an alternative to steel bars in reinforced concrete. Recently, India is also witnessing the manufacturing and use of such bars.

The Engineer in-Charge shall certify or obtain certification stating that the specific concrete elements reinforced with GFRP bars can meet the target criteria on serviceability, strength, and durability for the design life of such elements.
