This paper described behavior of deterioration of porous concrete containing natural zeolite as an aggregate and an admixture, subjected to freezing and thawing action. The freezing and thawing test was carried out based on the CIF testing method. Scaling and strain measured by an embedded gauge for the specimens are evaluated in this study. The behavior of scaling and deformation of the porous concrete containing the zeolite coarse aggregate was almost same as those of the specimen using crushed stone coarse aggregate. The deterioration increased when the zeolite powder used for the specimen, however usage of the natural zeolite as a coarse aggregate had inhibitory of the damage.
