“…Among the major components leading to acidic attack, mineral acids such as hydrochloric acid, nitric acid and sulfuric acid are most dangerous for concrete. Sulfuric acid is highly corrosive due to the fact that apart from the dissolution caused by hydrogen ions, sulfate ions tend to initiate sulfate attack (Hewayde et al 2007; Attiogbe and Rizkalla 1988;Ichitsubo et al 2006;Kawai et al 2005). Sulfuric acid is found in concrete sewer pipes due to the reaction between hydrogen sulfide and oxygen in the presence of aerobic sulfur oxidizing bacteria (Attiogbe and Rizkalla 1988;Ichitsubo et al 2006).…”

Natural ground water (Fattuhi and Hughes 1988 a), acid rain, etc., (Kong and Orbison 1987;Sersale et al 1998) may also be source of sulfuric acid.…”

The effect of an aggressive chemical environment on concrete prepared with ordinary Portland cement and silica fume, either as a binary combination or a ternary combination with fly ash, is investigated in the present study. The adverse environmental conditions are simulated by using either 1% sulfuric acid, 1% hydrochloric acid or 1% nitric acid. The corrosion process was monitored by measuring the mass loss and compressive strength for a period of one year. It was found that the course of action of acid attack is dependent on the type of acid and solubility of the calcium salt formed. The presence of mineral admixtures was found to lower the detrimental effect of all types of acids on concrete. Ternary mixes with OPC, silica fume and fly ash performed better than binary mixes containing only silica fume as supplementary cementitious material.
