| Abstract: | The composition and micro-structure of cement paste in electric field are investigated by instruments of XRD,DSC/TG,SEM/EDS and microhardness.The results show that in the initial stage,there is a large quantity of better crystallographic Ca(OH)2 with very high orientation near the cathode.However,the information of Ca(OH)2 becomes stable and the orientation of Ca(OH)2 gradually decreases with the extension of conduction time.The microhardness of the embedded pastes decreases at the beginning of electric fie... |
