Constitutive Relation of Sulfate Attacked Concrete Based on Uniaxial Loading
In this paper, the whole stress-strain curve of concrete attacked by sulfate and sulfate-chloride compound were investigated experimentally by an accelerated deterioration laboratory technique. For practical engineering applications, special attention of research was devoted to an ultrasonic nondestructive test (NDT) technique to estimate the damage extent. The curves were fitted very well with the same form of equations for the concrete suggested in the structure design code, but with different coefficients and value of feature points. Aanlytical expressions between the corrosion damage of concrete attacked by sulfate and the stress-strain relationship, constitutive parameters, value of character ponits,a series of mechanics parameters are achieved, which can be directly used in theoretical and numerical analysis as well as practical engineering detection and assessment of concrete structures attacked by sulfate.
