ABSTRACT
At present, both in China and abroad, there has been little study on the strength and deformation properties of super-high-strength high performance concrete. What has been conducted has investigated the strength or single deformation indices of the lower class of super-high-strength high performance concrete. Consequently, the data are limited and scattered. Today, only in Norwegian and German standards are there specications for the lower class of concrete in the super-high-strength concrete category. In the Norwegian standard, NS 3473E, the highest strength class is C105, while in the Guide to High Strength Concrete issued in 1995 by the German Concrete Association, the highest strength grade is C115.
