N2 - Carbonation test was carried out on the cement paste specimens with fly ash content of 0% to70%. The change rules of pore structure of cement paste with different fly ash (FA) content before and after carbonation were studied by means of microscopic test, which included mercury intrusion porosimetry (MIP) test and Brurauer Emmerr Teller (BET) test. It is found that total porosity, harmful holes' prosity (pore diameter>50nm), as well as most probable pore diameter and average pore diameter increase obviously when the content is above 40%, and a certain two order function relationship between the CO2 gas composite diffusion coefficient and the content of FA is presented.
