Research and Application of Integral Pouring and Crack Control Technology for Super Long and Large Volume Concrete Structure
In this paper,the causes of cracks in mass concrete are analyzed.Taking a specific project as an example,a comprehensive and effi-cient technical scheme is proposed to improve the crack resistance of concrete by optimizing the mix ratio,pouring,vibrating,curing,tempera-ture monitoring and temperature post-pouring belt.This scheme can effectively reduce the internal temperature of mass concrete and reduce the occurrence of cracks.After optimizing the temperature post-pouring belt into expansion strengthening belt,the process is simple and can fur-ther shorten the construction period,which is of great engineering application value.
