Case Analysis of Single Point Burst on Concrete Surface
A large area of concrete surface point like cracking occurred in a certain project's concrete structure.Through on-site sampling,strength volume stability and X-ray fluorescence composition analysis(XRF)tests were conducted on the affected concrete.The results showed that there is a potential danger of free calcium oxide in the affected area,and the large amount of free calcium oxide may be caused by the use of unqualified steel slag in the concrete.
