- Abstract
- A workshop on high-performance concrete (HPC) was held in Gaithersburg, MD on May 16, 17, and 18, 1990. The workshop was co-sponsored by the American Concrete Institute. High-performance concrete was defined as concrete having desired properties and uniformity which cannot be obtained routinely using only conventional constituents and normal mixing, placing, and curing proactices. The workshop objectives were to: [*] Identify currently and planned research programs on HPC; [*] Identify potential applications where HPC could be used on a routine basis; [*] Identify the technical barriers to widespread use of HPC; [*] Identify institutional barriers and deficiencies in standards which hinder the use of HPC; [*] Develop a listing of critical research to overcome the technical barriers and provide a sound basis for the needed standards. To achieve these objectives, noted international experts in concrete technology were invited to participate in the workshop. Eight working groups were organized to address different topics. This report summarizes the discussions and conclusions of the working groups. Each chapter begins with a brief introduction providing background on the nature of the problems addressed by the working group. Specific research topics are identified, and discussions are provided to explain the rationale for the needed research. The recommended research is proposed as the basis for a national program to exploit the potential of high-performance concrete and ensure U. S. competitiveness in concrete technology. Recommendations for implementing the plan are provided.
