A review of autogenous shrinkage models of concrete

For concrete with low water-to-binder ratio, the autogenous shrinkage often takes up most of the total shrinkage. In restrained structures, this kind of shrinkage will produce tensile stress. Once the tensile stress exceeds the tensile strength, it will lead to cracks and seriously endanger the durability of the structure. In this paper, the updated autogenous shrinkage prediction models of concrete in recent years are reviewed in detail. By comparing and analyzing these models, the latest research progress of autogenous shrinkage models is understood, and a direction for the subsequent research of autogenous shrinkage models of concrete is provided. Finally, the problems existing in current autogenous shrinkage models are summarized and prospected.
