Abstract EN
Concrete material has been a choice for the construction structures, even in the cold regions and saline zone.
However, these environmental factors have critical damaging effect on the concrete characters.
Consequently, this damage will decrease the servicing time of the concrete construction within this environment.
In order to evaluate the durability of concrete, the behavior of concrete specimens under the sulfate solution corrosion attacks was studied in this presented work.
Two groups of the specimens were immersed into the sulfate solutions with a concentration of 10% and 20%, respectively.
The strength development of the specimens under different immersing time was studied.
Based on Fick’s law, a steady diffusion equation for sulfate ions in concrete was presented, and the depth of penetration of the attacking sulfate ions was also determined.
Based on the depth of penetration and the definition of damage, a damage model for concrete material is developed and a new equation (strength-time) describing the chemical corrosion concrete material is proposed.
Results show that the suggested analytical methods can quantify the damage process of concrete under sulfate attack, and the power laws damage developing formula can be used to describe the damage development of the concrete construction subjected to chemical corrosion.
