High Performance Concrete (HPC) Bridge Project for SR 43

摘要

The objective of this research was to develop and test high performance concrete mixtures, made of locally available materials, having durability characteristics that far exceed those of conventional concrete mixtures. Based on the results from the development of high performance concrete, guidelines for a high performance concrete bridge over Burnett Creek on SR 43, just north of I-65 near West Lafayette, Indiana, will be prepared. In addition, the effects of different curing conditions, with respect to temperature and moisture conditions, were evaluated. The use of 15.2 mm (0.6 in) prestressing strand in girders made of 69 MPa (10 ksi) concrete was also evaluated with respect to pullout resistance and transfer and development lengths.
