Structural Concrete Design and Curing Investigation

摘要

This research focused on the investigation of deck cracking as a function of the mix design and curing conditions. It is believed by some that reductions in the shrinkage of the concrete deck mix by as little as 20% would reduce the concrete bridge deck cracking significantly. For this research, this reduction in shrinkage was sought through adjustments in the mix design or better curing practices. Obtaining this objective involved a literature review of previous research, documenting the curing practices and performing material tests of three bridges within the state of Utah that represented different regions. The final goal of the research was to improve upon the deck concrete mix design and current curing practices for future bridge decks.
