Engineering 2021, Volume 7, Issue 3,   Pages 348-357 doi: 10.1016/j.eng.2021.01.006

Abstract:

The complex compositions and large shrinkage of concrete, as well as the strong constraints of thestructures, often lead to prominent shrinkage cracking problems in modern concrete structures.Second, three new key technologies are illustrated: temperature rise inhibition, full-stage shrinkagecompensation, and shrinkage reduction technologies.These technologies can efficiently reduce the thermal, autogenous, and drying shrinkages of concrete.
