| Abstract: | The carbonation rate, the strength and the permeability of concrete with different addition fly ash have been studied in this paper. The relationship of the addition of fly ash and its pozzolanic reaction to the carbonation rate of fly ash concrete has been analyzed. The cause of the changes of the strength and permeability of fly ash concrete before and after carbonation has been discussed. |
