Abstract

High strength hydraulic concrete was introduced based on its thermo-dynamic and strain-stress characteristics. The compound exponential thermo-dynamic creep model was established. The temperature rise models were interpreted. The bisection constitutional model was deduced as the approach to express the strain-stress non-linearity of high strength hydraulic concrete. The key parameters on thermo-dynamic characteristics and strain-stress ones of high strength hydraulic concrete were offered. The models and parameters in this paper are useful for engineering application and theoretical research.

Keywords: High strength hydraulic concrete, non-linear model, thermo-dynamics.
