초록
As form a part of way to improve the durability of concrete placed on deleterious environments such as acidic rivers, sewage wastewater, and sewer system, the paper presented here is the results of experimental immersion test, and for the test solution, 4 types sulfuric acid solution was prepared. From the result of EDS analysis of cement paste at 180 days of immersion, the detected major chemical elements were Ca and S and they are assumed as composing elements of gypsum. A comparative study between prediction models from the Japanese Standard and the present study corresponding to
