BENEFITS OF LIGHTWEIGHT HPC
Thomas A. Holm and John P. Ries, Expanded Shale Clay and Slate Institute There are many advantages to the use of lightweight aggregate in high performance concrete. This article highlights the primary design- and construction-related benefits. Improved Structural Efficiency (Strength/Weight)
HPC REPEAT SUCCESS IN NEW HAMPSHIRE
Mark D. Whittemore, New Hampshire Department of Transportation The success of New Hampshire’s first high performance concrete (HPC) bridge—Route 104 in Bristol(1)—made the decision to proceed with the next HPC bridge an easy choice. Actually, during New Hampshire’s early involvement
A STRATEGIC PLAN FOR HPC BRIDGES
Basile G. Rabbat, National Concrete Bridge Council During the last 15 years, research performed on high performance concrete (HPC) has led to the construction of a number of HPC bridges in the United States. In the late 1980s, the Strategic
