| Outline of Final Research Achievements |
Ceramic porcelain insulators discarded from electric power companies and railway companies are one of the materials possibly recyclable as aggregates in construction materials. In this study, the utilization of the ceramic waste aggregate (CWA) for mortar and the development of the CWA mortar as an eco-efficient construction material using ground granulated blast-furnace slag (GGBS) are aimed. The mechanical test, the chloride immersion test, and the pore size distribution test were performed on the CWA mortars partially replaced with GGBS. The various strength relations were represented. Moreover, it was revealed that the apparent chloride diffusion coefficient was well related to the cumulative pore volume less than 0.1 micro-m of pore diameter.
