The characteristics of the concrete cover should ensure alkaline protection for the steel bars but should also be able to combine CO2 to a certain depth. Pull Kit Tester, Linear Transducer, Concrete Test Hammer, Seismic Monitoring, Concrete NDT System, NDT Equipment, Pile Testing System, etc. This reaction is known as carbonation. The pH across different areas of cured concrete can vary. This website is for the great majority of us who aren't university professors of cement chemistry but whose work requires a good understanding of the subject. Carbonation of concrete occurs when the carbon dioxide, in the atmosphere in the presence of moisture, reacts with hydrated cement mineral to produce carbonates, ex.
