Evaluation of Autogenous Shrinkage of HPC Based on AHP-Fuzzy Method

In order to evaluate the influence of material constitutes and mix design on the autogenous shrink- age of high performance concrete,this paper brings forward a new method of autogenous shrinkage evaluation based on AHP-Fuzzy method.It contains two steps:First,utilizing the AHP theory,we set up the estimated system and fix the proportion in each target;Second,we calculate the score by using the Fuzzy comprehensive appraisal and the score is defined as the autogenous degree.By validating to the experimental result,we find that the more the score of autogenous degree is,the more the autogenous shrinkage ratio is.Therefore,this method has important significance for the diagnosis of concrete autogenous shrinkage.
