Abstract:Based on the test to optimize shrinkage compensating mix proportion, limited expansion ratio verifying test and contrast test were carried out to verify the authenticity and reliability of results about the limited expansion ratio test. At the same time, based on optimal concrete mix proportion, tests were carried out including the permeability test, the chloride ion penetration resistance test and the test to study the influence of fiber varieties and dosages on early crack resistance of shrinkage compensating concrete. Based on the test results, the fiber varieties and dosages of the application in this project were determined.

Keywords:shrinkage compensating fiber reinforced concrete; anti-cracking performance; durability; anti-permeability
