Plastic Shrinkage Cracking in Concrete [PDF]
Proceedings, 2019 Plastic shrinkage cracking in concrete is mainly a physical process, in which chemical reactions between cement and water do not play a decisive role. It is commonly believed that rapid and excessive moisture loss, due to evaporation is the primary cause

Modelling the Severity of Plastic Shrinkage in Cementitious Materials [PDF]
Proceedings of the International Conference on Civil Infrastructure and Construction (CIC 2020), 2020 "Plastic shrinkage cracking in cement-based materials occurs between the mixing and the final setting of the mixture, where rapid evaporation of the mixed water is the main cause behind the phenomenon. The induced cracks may impair the durability and sustainability of the structure by facilitating ingress of harmful materials into the concrete bulk. In

Effect of steel fibers on plastic shrinkage cracking of normal and high strength concretes
Materials Research, 2010 Naturally concrete shrinks when it is subjected to a drying environment. If this shrinkage is restrained, tensile stresses develop and concrete may crack. Plastic shrinkage cracks are especially harmful on slabs.
