This study describes results on immersion tests of cement concrete specimens incorporating a ground granulated blast-furnace slag of which weight ratio to cement was 60 to 80%. The specimens were soaked into sulfuric acid hot spring and hydrochloric acid river at Hachimantai area in Akita prefecture. Parameter of specimen was water-binder ratio, incorporating ratio of the ground granulated blast-furnace slag, sand percentage, type of fine aggregate and type of coarse aggregate. Furthermore, unsaturated polyester polymer concrete was also examined. Although the immerse tests environment was very strict for the specimens because of a high temperature and a low pH, incorporation of the blast furnace slag powder could be repressible mass loss of the specimens. The polymer concrete had no deterioration due to the tests.
