| Abstract: | The hydrated products and pore size distribution of high road fly ash cements were studied by means of XRD,DTA,Mercury porosimeter,etc.,The experiment results showed that C-S-H gel,AFt were the main hydrated products in high road fly ash cement,but the contents of Ca(OH)２ were lower.The exothermic peaks of the formation of AFt and AFm appeared in hydrated exotermic curves of this cements,while the peaks of C-H-S gel and Ca(OH)２ were not.Although the total porosity of this cement stone were higher,the volume porosity of large pores which sizes were more than 1000A。 were lower after 7 days,the micropores and gel pores which size were little than 500A。 were higher.Thus,the cement stone was fine and close in texture,properties were also higher in late ages. |
