| Abstract: | Reinforced concrete crack control is one of the most important problems of construction engineering.Especially in the last 20 years,after pumping concrete products being widely applied,concrete homogeneous improves a lot,at the same time,the difficulty of crack control technology increases greatly.In this paper,based on a lot of construction practices and field experiment researches,the causes of crack caused by deformation,the restrained deformation characteristics,the design criterions and comprehensive technical measures are summarized. |
