Interfacial Transition Zone Characteristics of Light-Burnt MgO Concrete

Abstract:

Article Preview

The morphology and elements enrichment in the vicinity of interfacial transition zone was investigated with employment of SEM, EDS and BEI. Results indicated that the morphology of products of hydration in ITZ area and cement matrix was similar but differed in amount, size and crystal features. Elements Ca, Si, Al and Mg had tendency to enrich in ITZ zone but differed in accumulation extent in orders. MgO was non-uniformly distributed in concrete, fully mixed in construction though, richer in cement matrix than in ITZ, yet MgO later inclined to migrate to ITZ area and the gap in between was mitigated with in-depth hydration.
