Sub-working group 1 of the Japan Concrete Institute (JCI) committee on Utilization of High-Strength Concrete (HSC) and High-Performance Concrete (HPC) (JCI-TC063A) has been working on collecting information from research on HSC and HPC as well as their practical use. The committee published a report in 2006 in Japanese. The objective of the report is to present state-of-the-art information on concrete with strengths in excess of about 60 MPa and high-strength steel reinforcement such as prestressing steel, excluding concrete made with atypical materials, such as fibers, or uncommon techniques. It primarily addresses the mechanical properties of high-strength concrete and high-strength steel reinforcement. A concise digest of the report has already been published as a keynote paper in the proceedings of 8th International Symposium on Utilization of HSC and HPC in October 2008 in Tokyo. This paper is based on the keynote paper with additional information on High Strength Steel, HSS, reinforcing bars in Japan.
