Estimation of the Porosity of Portland Cement Pastes Using Backscattered Electron Images

It is widely recognized that the porosity of a material exerts an enormous influence on its physical properties. In this study, the determination of porosity has been measure by two methods, by methanol exchange and by a backscattered electron image. The work was done on an ordinary Portland cement paste. The results show that backscattered electron imaging can be used to determine the porosity of Portland cement pastes, and the technique can be used as a powerful tool to determine the essential factor of durability in concrete materials.
