| Abstract: | The mechanical properties and condensation polymers of red mud-metakaolin cementitious materials using high calcium fly ash as an additive were investigated by XRD,IR,SEM and EDS analysis.The results show that near 14% high calcium fly ash cause the mechanical properties of red mud-metakaolin cementitious materials increase,and the condensation polymers of red mud-metakaolin cementitious materials are Gismondine,unnamed zeolite,pyrophylite,CaAl2Si2O8,kynite,C-S-H and halloysite-10A.With the prolongation of ... |
