Carbonation of concrete | PPT

Change in Ph value The pH of the fresh cement paste is at least 12.5. The atmospheric carbon dioxide diffuses into the hardened concrete through pores and when carbonation reaction takes place, the alkalinity of the concrete reduces. The pH of a fully carbonated paste is about 7. Means in carbonated zone the Ph range below 9.2.
