| Outline of Final Research Achievements |
The results on the study are mentioned in the Part I and the Part II in the report. Natural zeolite caused frost resistance to porous concrete and cement mortar due to it’s nano-size-level pore, especially when it was used as an aggregate, as same as performance the AE agent used to the concrete.
That behavior explained that the pore may control the Driving-Force of unfrozen water, and then the study on the Driving-Force has to be carried out in near future. This study showed the basic date for the further study.
