Cost and Ecological Feasibility of using UHPC in Highway Bridges

项目名称：	Cost and Ecological Feasibility of using UHPC in Highway Bridges
摘要：	There is a growing interest in expanding the use of ultra high performance concrete (UHPC) from bridge deck joints and connections for accelerated bridge construction to other components and applications. Currently, most of the available UHPC mixes are proprietary mixes that relies on steel fibers from international suppliers and costs up to $2000/yd3, which is almost 20 times the cost of conventional concrete ($100/ yd3). Moreover, the high cement content in UHPC and the massive energy consumption associated with its production raise concerns about the ecological feasibility of expanding the use of UHPC in the built environment. On the other hand, the higher strength and durability of UHPC should result in more compact cross-sections, safer structures, and longer service life compared to the conventional concrete. This study considers different UHPC mixes to design a bridge pier (a multi-column bent) and analyze its cost and ecological feasibility for future optimization of UHPC mixes.
