In this paper, an experimental program has been conducted to investigate shrinkage of fast hardening concrete (FHC) which is used to replace the existing ballasted track with concrete track. In the test, curing method was considered as a test variable. The test results indicated that autogenous shrinkage was dominant on FHC while drying shrinkage was negligible. To represent shrinkage of FHC, a new model has been proposed through regression of the test results.
