Paper Title:
Test and Analysis of Expansive Deformation for Shrinkage-Compensating Steel Fiber Reinforced Shotcrete
  Abstract

In order to research the expansive deformation performance of shrinkage-compensating steel fiber reinforced shotcrete, orthogonal test was done in this paper with expansive agent content and steel fiber content as variable. And the test results showed that restrictive expansion ratio was gradually increased when curing in water, while reducing in air. The difference between restrictive expansion ratio and free expansion ratio used to make self stress by stretching steel bar and steel fiber. Meanwhile the maximum self stress is 0.58MPa, and the minimum self stress is 0.23 MPa in concrete. What’s more, both the maximum self stress and the minimum self stress could meet the requirements for self stress of shrinkage-compensating concrete.
