- Synopsis
- Self-compacting concrete with high strength and high durability has been on the practical stage as a technique extending the life span of structures. Self-compacting concrete with high strength and high durability is also called Super Quality Concrete (S. Q. C), which is defined as concrete with W/B less than 40%, expected compressive strength more than 60 N/mm2 and having self compacting workability. The new technical information about mechanical properties and durability performance of members combined Super-Quality-Concrete and deformed-bar with high strength more than 700 N/mm2 has been recently obtained through various experiments. Reflecting these experimental results, the guideline for design and construction has been almost completed and will be published soon. Advanced points of this guideline are 1) it is based on performance evaluation technique, 2) it includes Design, Construction, and Maintenance Manual, 3) an example of trial design is included as an appendix, and so on.
