Abstract:
Due to an industry wide effort, high-strength reinforcement (HSR) up to Grade 100 is now allowed by ACI 318-19. To date, the ACI Foundation, Charles Pankow Foundation, Concrete Reinforcing Steel Institute, and others have provided more than $3 million in combined funding for HSR research projects.
