Abstract:
Straight Portland cement concrete and other concretes containing fly ash or a chemical water-reducing agent were investigated for the rate of carbonation. Results have indicated that concretes having the same strength and water/cement ratio do not necessarily show the same rate of carbonation. For a strength level of 25 MPa, concrete containing fly ash carbonated 50% faster than the straight Portland cement concrete.
