| Outline of Final Research Achievements |
The purpose of this is to clarify the adequate evaluation of the carbonation resistance for the concrete containing mineral admixture such as fly-ash or blast furnace slag, the accelerated carbonation test and the pore distribution test were done by various curing periods and curing methods. As a results, the carbonation rate of plain concrete and fly-ash concrete were constant, although the pore volume become small by long curing. And the carbonation rate of every concrete was fast, in case of curing that the air dried at 40 degrees Celsius or the wet-dry-cycle. The larger the containing ratio of blast furnace slag, the faster the carbonation rate.
