Assessment Model of Concrete Durability in Complicated Environment

In this paper, the rule of index weight is determined by analyzing the existing rules of life assessment for concrete. Based on fuzzy decision making of binary comparison, the weight of different factor taking effect in complicated environment can be analyzed. With known effects of each factor, the classification and score of concrete durability can be made. Thus the assessment of concrete durability in complicated environment can be modeled. The model is used to predict the service life of concrete and provide optimize mix proportion design.
