| Summary: | This paper presents the relationship between the crack width formed in MgO cement and the
type of hydrated magnesia cement(HMC) formed. These crack widths were created using
sandpaper and G-clamps. There were four range of crack widths used to evaluate this
relationship, namely: less than 50um, 50-100um,100-150um and more than 200um.
Upon having the precipitated HMCs, chemical analysis of the HMCs is done using SEM, EDX
and TGA analysis to determine the morphology as well as the chemical composition of these
HMCs microstructures. In addition, the carbonation depth within each crack width sample is
also evaluated to determine the effectiveness of the carbonation process within each crack width. |
