Concrete structures designed to meet blast criteria often require substantial increases in structural system size, weight, and cost when using conventional materials, but using higher strength materials may offer a way to mitigate these increases while achieving desired performance levels. The primary objective of this research is to investigate the performance of a high-strength Portland cement concrete, high-strength low-alloy vanadium (HSLA-V) rebar material combination that meets or exceeds blast resistance criteria while allowing a more efficient structural design than can be achieved using conventional materials. Twelve panels consisting of both single and double mat conventional Grade 60 rebar or HSLA-V rebar in combination with 4 ksi or 15 ksi concrete were tested using the ERDC quasi-static water chamber.
