On the basis of the mix proportioning method recommended by Technical Specification for Application of Self-Compacting Concrete (JGJ/T 283-2012)and using the local materials,self-compacting concrete with strength grades of C50-C60 are successfully produced. Some basic mechanical properties of the concrete such as the stress-strain curve in uniaxial compression,the peak strain and the Poisson’s ratio are further experimentally determined. This study provides some useful basis for encouraging the practical application of self-compacting high performance concrete.
