This study aims at evaluation of compressive strengths and coefficients of chloride ion diffusion in concrete specimens using plain, chemical admixture PNH deveoped for anti-chloride corrosion, commercially available product of B company and blast furnace of granuate slag(BSF). It is found throughout experiments that most cases of compressive strengths are almost similar except using BSF, but the PNH has the highest resistance against chloride attack.s
