%X In the study, different mineral additive concretes were investigated under air, 3,5% seawater and 5% sulfuric acid environments considering the parameters of total binder amounts and equivalent water/cement ratio together. For this purpose, control concrete (K), and concretes including fly ash (U), slag (C), fly ash and silica fume (US) were produced. The equivalent water/cement ratio for control concrete and concrete with fly ash was 0,45 and binder amounts were 400 and 470 kg/m3, respectively. The equivalent water/cement ratio for concrete with slag, concrete with fly ash and silica fume was 0,53 and binder amounts were 500 and 440 kg/m3, respectively. The equivalent water/cement ratio was calculated using TS13515 standard. Chemical resistance was determined via visual inspection, change in weight and compressive strength. According to the results, concrete with fly ash and silica fume showed superior chemical resistance while it had higher equivalent water/cement ratio and lower binder materials. The concrete with slag and control concrete showed the lowest performance due to the higher CaO content. The equivalence coefficient defined by TS13515 standard for fly ash showed good results with experiments; however, significant recommendations have been made to the standard for the calculations of equivalent water/cement ratio of concretes with slag and silica fume
