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
