Paper Title:
Shrinkage Cracking Test and Analytical Model for Concrete Considering Creep Behaviour at Early Age
  Abstract

Cracking due to the restrained shrinkage stress has been frequently observed at early age in concrete construction. The early-age shrinkage cracking reduce the structural performance of concrete and may accelerate deterioration to shorten the service life. Two kinds of strategies and instrumentation have been developed to assess early age cracking: ring tests with a restraining core, longitudinal tests where the restraint is at the end grips of the specimen. Early-age concrete exhibits creep or relaxation behavior that is a typical response of viscoelastic materials. Viscoelastic constitutive model should be used to analyze stress development of the restrained concrete. The assessment of the risk of cracking can be based on the model with input of the estimated concrete deformation.
