| Abstract: | The carbonation depths of the pulverized slag powder mortar,flyash mortar and slag\|flyash combination mortar are measured systematically.The meso\|scope and micro\|scope mechanisms of the increase in the carbonation resistance of flyash mortar due to pulverized slag powder are analyzed by porosity,Ca(OH)\-2 content of the paste and permeability resistance of the mortar.It is the most economical and effective measure to increase the carbonation resistance of flyash cement\|based materials by the combination of pulverized slag powder and flyash. |
