摘要	Concrete is the most commonly used building material at present. The operational reliability of concrete structure has a close relationship with the attenuation of its material performance. Along the long coastline of China and in the large saline land in western China, lots of concrete buildings suffer the erosion of sulfate ion and chlorine ion as well as the “super-composite effect” of dry-wet cycling, because of which the concrete buildings in these areas begin to crack and pall before reaching their design life, which gives a serious threaten to their safe operation. Through the analysis, a prediction model for concrete durability attenuation was put forward based on the theory of the grey system. It is a prediction model of concrete mechanical property under the conditions of sulfate attack and dry-wet cycling established by using the Grey System Theory and taking the dynamic elasticity modulus gained in the laboratory test as the parameter indicators evaluation of concrete durability attenuation, and its average relative error has been got. The study results show that the application of this model to predict concrete performance attenuation has high precision and good applicability, which provides technical references for the erosion prediction of concrete in the similar surroundings. © 2015 CAFET-INNOVA TECHNICAL SOCIETY.
