Abstract:

Concrete with a unit weight between that of traditional lightweight ; concrete (LWC) and normal weight concrete (NWC) ; is not covered in the American Association of State Highway ; Transportation Officials (AASHTO) Load and Resistance Factor ; Design (LRFD) Bridge Design Specifications.(1) This research ; program includes a significant number of bond strength tests ; on this type of concrete. The results from this research project ; are included in a database that covers a broader range of unit ; weights in order to determine trends for LWC as a function ; of unit weight. New design expressions for the development ; length of mild steel in tension are proposed for LWC that ; include a modification factor for LWC based on unit weight.
