Abstract

Abstract

The cracking sensitivity of concrete is determined by the stress development at early age,and the creep of young concrete is an important factor influencing the development of restrained stresses in concrete structures due to autogenous contraction and thermal deformation.It is studied that the properties of creep in restrained concrete at early age,and the effect of creep/relaxation on cracking sensitivity of concrete.
- creep/relaxation,
- shrinkage,
- restrained condition,
- cracking sensitivity
