GFRP Reinforced UHPC Composites for Sustainable Bridge Construction

摘要

Rehabilitation of bridge structures damaged by continuous wear as well as time-dependent and environmental effects is a major concern for a large number of reinforced concrete and prestressed concrete bridge structures. Every year in North America, billions of dollars are spent to repair and maintain bridges. As bridge structures ages, cost of repairs and maintenance magnifies. Conventional structural concrete with steel reinforcing bars can significantly deteriorate with time requiring regular and often costly maintenance. The construction of bridge structures with ultra-high performance concrete (UHPC) and glass fibre reinforced polymer (GFRP) bars can solve premature deterioration due to corrosion of reinforcement, increase the service life and lead to sustainable bridge construction.
