STUDY ON MECHANICAL PROPERTIES OF C100～C150 SUPER HIGH STRENGTH AND HIGH PERFORMANCE CONCRETES

摘要

In this paper the strength and deformation properties of super high strength and high performance concretes such as splitting strength, bending strength, bond strength with reinforcement, prism strength, characteristics of stress-strain relationship, modulus of deformation and Poisson ratio etc are systematically studied taking the C100～C150 super high strength as representative. The regression equations of compressive strength with various strength indexes, deformation modulus and peak strain are obtained. Comprehensive knowledge and understanding of mechanical properties of super high strength are gained, which gives a foundation to application of super high strength concretes in the future.
