Guidelines for concrete mixtures containing supplementary cementitious materials to enhance durability of bridge decks.

This report presents guidelines to facilitate highway agencies’ use of supplementary cementitious materials to enhance durability of concrete used in highway construction, especially bridge decks. Encompassed in these guidelines is a methodology for selecting optimum concrete mixture proportions. The methodology focuses on durability aspects of http://onlinepubs.trb.org/onlinepubs/nchrp/nchrp_rpt_566.pdfconcrete and the performance requirements for specific environmental conditions and is presented in a text format and as a computational tool, in the form of a Visual Basic–driven Microsoft® Excel spreadsheet. Background information, a user’s guide, and a hypothetical case study are also available. These guidelines should be of interest to state engineers and others involved in the design and construction of concrete bridge decks and other structures incorporating supplementary cementitious materials.
