Source:PIB ↗

हे का महत्त्वाचे आहे

This article highlights the practical application of cutting-edge construction technologies like UHPFRC in India's public infrastructure, directly aligning with GS3 syllabus requirements on infrastructure development, technological innovation, and urban mobility.

सारांश

Union Minister Nitin Gadkari announced the completion of the Indora Chowk-Dighori Flyover in Nagpur, constructed using advanced Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) technology. The project significantly cuts down urban commute time and showcases India's shift toward high-tech, durable, and rapid infrastructure engineering materials.

मुख्य मुद्दे

  • The Indora Chowk-Dighori Flyover in Nagpur has been completed using Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) technology.
  • The project reduces travel time between Indora and Dighori from 1 hour to just 10-15 minutes, easing urban congestion.
  • UHPFRC technology enhances structural durability, reduces maintenance needs, and allows for innovative structural designs with smaller cross-sections.
  • Emphasizes the Indian government's push towards adopting advanced engineering materials and innovative construction practices in infrastructure development.

Science and Technology Advanced Materials

What are the defining characteristics and advantages of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC)?

  • High Strength: Exceeding 150-200 MPa compressive strength combined with high tensile ductility through dispersed steel fibers.
  • Durability: Extremely low porosity prevents ingress of water and chlorides, giving lifespans exceeding 100 years.
  • Slim Profiles: High strength-to-weight ratio allows thinner beams, reduced dead loads, and longer spans than conventional RCC.

आंतर-विषय नमुने

  • Advanced Infrastructure Materials and Green Transitions

    UHPFRC adoption aligns with India's Nationally Determined Contributions (NDCs) under the Paris Agreement by lowering long-term cement intensity and lifecycle emissions in urban transit corridors.

  • Urban Mobility and PM Gati Shakti Synergy

    Fast-track urban flyover construction directly impacts Ease of Living Index parameters and PM Gati Shakti multimodal connectivity targets in tier-2 cities.

UHPFRC properties (high compressive strength, low permeability, 100+ yr lifespan) will likely feature in a science/tech material science match.
