Cause analysis of local concrete bursting of shear walls in a basement
The influence of f-CaO on concrete quality has been largely controlled,but there are still other factors affecting concrete quality.In order to analyze the cause of local concrete bursting of the shear walls of a certain building basement,based on the judgment method of Technical standard for inspection of building structure(GB/T 50344-2019),it was found that f-CaO in the concrete did not exceed the limit.X-ray fluorescence technology was used to quantitatively analyze the chemical composition.The cause of concrete bursting was analyzed,and the concept of"agglomerated unhydrated CaO"was introduced accordingly.
