Grey Prediction on E1astic Modulus of Concrete Corrosion Under Acid Rain

Elastic modulus is an important mechanical parameter of concrete. To investigate the elastic modulus of concrete under acid rain environment, Grey theory metabolic GM（1, 1） model was applied in this paper. A Grey model GM（1, 1） was established to predict the elastic modulus of concrete corroded under acid rain, and the model is investigated through its ability to reproduce available experimental trends. The analytical results of the oretical model was in accordance with the experimental data. It is shown that metabolic GM（1, 1） model put forward in this research is a feasible and reliable model for the prediction of the elastic modulus of the concrete corroded under acid rain.
