Abstract:

The purpose of this report is to present the measured properties and comparison between concrete mixtures consisting of different available supplementary cementitious materials (SCMs) for the purpose of understanding which SCM provides the best chloride resistance for bridge decks in Utah. The concrete batches were created in the Utah Valley University laboratory, with the original mix design aimed at replicating the proportions used in the Salt Lake City Airport parking garage constructed in 1990. This original design consisted of 9% of the replacement of cement by a silica fume. The recreated mixtures consisted of up to 15% replacement of cementitious content. The SCMs studied including three types of silica fume found across the country, two fly ash sources, a local pozzolan, and a locally collected waste glass dust. A control with no SCMs was also created for comparison. Properties measured were slump, unit weight, air content, compressive strengths at 7 and 28 days, and rapid chloride permeability after 1 year age. Overall, the study showed the silica fume mixtures outperformed in strength and rapid chloride permeability significantly over the other SCMs.
