The Evaluation to Influence Factors of Concrete Durability Based on Grey Correlation Degree Method

Abstract:

In this paper, under the environment of saline soil in the western region of Jilin Province, a series tests research on the durability of concrete has been made. The test results show that: there are a lot of factors that influence the durability of concrete, including the concrete itself internal factors and the external environmental factors. The correlation degrees between these influence factors and the durability of concrete are uncertain. In this paper, a grey correlation degree method has been used to analyze the correlation degrees between these influence factors and the dynamic elastic modulus loss rates of concrete, in order to determine the influence degree of each factor on the durability of concrete.
