| 摘要： | The primary objective of this research is to identify high performance concrete (HPC) mix proportions that are suitable for transportation infrastructure in New Jersey. Two classes of concrete with compressive strengths ranging from 6 to 12 ksi are developed. Extensive information is available in the literature covering various aspects of HPC. Show case projects have been built in a number of northeast states including New Hampshire and Virginia. The research plan involves: (1) review of existing information, (2) selection of mix proportions suitable for New Jersey using local aggregates and the proportions in Class A concrete, (3) evaluation of trial mixes prepared in the laboratory and at least one ready-mix industry, (4) evaluation of mechanical and long-term properties, and (5) preparation of specifications for the implementation of HPC in future projects. |
