Determination of critical moisture content for carbonation of concrete

The concept of effective buffering capacity is fundamentally not new and has been used before by Hobbs, (1988) and (Parrott, 1994), but not as the unique parameter for predicting carbonation rates as shown by long-term carbonation data by Wierig, (1984), Hobbs, (1988 and 1994) and Skjolsvold, (1986). Therefore the w/b or some other determinant of the physical properties of the concrete would also be influential.
