Feasibility of Non-Proprietary Ultra-High Performance Concrete (UHPC) for use in Highway Bridges in Montana

Started: April, 2015 Ended: May, 2017 Project ID #4W5387 Status: Completed

Objective

The objective of the proposed project is to develop and characterize non-proprietary ultra-high performance concrete (UHPC) mixes to determine whether UHPC is a cost effective, viable option for Montana bridges.

Abstract

Ultra-high performance concrete (UHPC) has mechanical and durability properties that far exceed those of conventional concrete. Thus, elements made with UHPC have longer service lives, decreased maintenance costs, and are thinner/lighter than elements made with conventional concrete.  However, using UHPC in conventional concrete applications has been cost prohibitive, with commercially available/proprietary mixes exceeding $2,000 per cubic yard, which is about 20 times the cost of conventional concrete.  The proposed research will aim to develop and characterize non-proprietary UHPC mixes made with materials readily available in Montana.  These mixes are anticipated to be significantly less expensive than the commercially available UHPC mixes, thus allowing for the use of UHPC in construction projects in the state.  In particular, the Montana Department of Transportation (MDT) Bridge Bureau is interested in using UHPC as a field-cast jointing material between precast concrete deck panels and girders and between the flanges of adjacent girders. The objective of the proposed project is to develop and characterize non-proprietary UHPC mixes to determine whether UHPC is a cost effective, viable option for Montana bridges. This objective will be met by first developing UHPC mixes with materials readily available in Montana.  These mixes will then be evaluated via a suite of mechanical and durability tests to fully characterize their performance.  This evaluation will also include an assessment of the cost of these new mixes.  The results of this study will then be analyzed, and a final report will be prepared.
